CryoTong™ – Long
ApplicationsCrystal transfer under cryo temperature
FeaturesArtery clamp style closure30 seconds of cryo temperature180 mm length
Description
The CryoTong is a tool used to manually transfer a crystal mounted on a CrystalCap™ from liquid nitrogen to a magnetic base in a goniometer head positioned in a cryogenic stream, and then back to liquid nitrogen. The one-piece, compact CryoTong is available in two lengths. The long CryoTong is approximately 180 mm in overall length. The artery clamp style maintains the CryoTong in the closed position until the clamp is squeezed, which opens the opposing heads. The heads are non-magnetic stainless steel. The handle is magnetic stainless steel. The inside of the head is machined to closely surround the CrystalCap with loop and crystal in place. A small retaining lip is machined into the lower portion of the head to prevent the CrystalCap from slipping out of the CryoTong when the tool is in the closed position. The CryoTong can maintain the temperature of the crystal at -160°C for up to 30 seconds during room temperature crystal transfers. Choose the proper CryoTong size based upon the pin length required by the configuration of the x-ray data collection hardware used. The 18 mm CryoTong (HR5-112) is to be used with the CrystalCap HT and any other CrystalCap configured for 18 mm.HR5-114 Long CryoTong 18 mm, 180° features the head in alignment with the handle of the CryoTong.

CrystalWand™ Magnetic
ApplicationsCrystalCap Magnetic & CrystalCap Copper Magnetic handling toolDescription
The CrystalWand Magnetic is designed to be used exclusively with the CrystalCap Magnetic, CrystalCap Copper Magnetic, and CrystalCap HT systems during transfer of the caps from the vial to the goniometer head and from the goniometer to the vial. The 6 1/2” (165 mm) long chrome plated steel wand features a plastic housing enclosing a spring tensioned plunger that when depressed, moves a non-magnetic steel platform away from the magnet housed in the end of the wand. This causes the steel CrystalCap to detach from the wand and be placed readily into the vial or the CryoTong™. When the platform is retracted, the wand securely holds the steel CrystalCap Magnetic. The CrystalWand Magnetic 45° (McMiken Tool) offers the same functionality but is bent at a 45° angle at approximately 2.5 cm from the magnet end.HR4-729 CrystalWand Magnetic, StraightHR4-315 CrystalWand Magnetic, 45° (McMiken Tool)

Features
 The original sparse matrix screen
 Sparse matrix formula efficiently samples salts, polymers, organics, & pH
 Proven effective with more than 1,000 biological macromolecules
 Tube or Deep Well block format

Description
The Crystal Screen and Crystal Screen 2 reagent kits are designed to provide a highly effective and rapid screening method for the crystallization of macromolecules. The screens are simple and practical for finding initial crystallization conditions. The initial crystallization conditions for more than 1,000 proteins, peptides, oligonucleotides, and small molecules have been determined using Crystal Screen.
A highly effective approach to overcome the exhaustive search for suitable crystallization conditions is the use of a sparse matrix method of trial conditions that is biased and selected from known crystallization conditions for macromolecules. The formulation utilized in Crystal Screen and Crystal Screen 2 evaluates 96 unique mixtures of pH, salts, polymers and organics, and their ability to promote crystal growth.
Crystal Screen contains 50 unique reagents, 10 ml each and is based on the sparse matrix formulation first described by Jancarik and Kim in 1991.
Crystal Screen 2, an extension of Crystal Screen, contains 48 unique reagents, 10 ml each and is based on the formulation first described by Cudney et al in 1994.

Description
Siliconized glass cover slides allow a droplet to be suspended in a position which provides near optimal conditions for vapor diffusion with the surrounding reservoir solution. These siliconized glass cover slides provide a consistent, high quality finish for crystallization experiments. The hydrophobic surface produces a drop which “stands well” and does not flatten on the glass. The siliconized surface prevents the adhesion of crystals and precipitate onto the glass surface. Use Dow Corning Vacuum Grease (HR3-510), Dow Corning 7 Release Compound (HR3-508), or immersion oil to seal cover slide to plate. Available in 12, 18 or 22 mm diameter circles and 22 mm diameter squares. Available in 0.22 mm or 0.96 mm glass thickness. The 0.96 mm thick slides are virtually unbreakable during crystallization handling.

Applications

Cryocrystallography
Features

Adjustable loop orientation
Synthetic CryoLoop on adjustable stainless steel MicroTube
MicroTube specially engineered with EasySnap notches
20 micron diameter nylon CryoLoop

Description
Similar to the Mounted CryoLoop™ in design and function, the Adjustable Mounted CryoLoop allows one to manipulate and orient the CryoLoop to multiple, unique positions previously unattainable with typical cryo setups. The Adjustable Mounted CryoLoop is a 20 micron diameter synthetic loop mounted inside a malleable stainless steel sleeve, which in turn, is mounted inside the EasySnap MicroTube™.
Using a specially designed L-shaped tool (HR5-902) with a positioning notch, one can manipulate the angle and orientation of the CryoLoop by bending and adjusting the angle of the malleable stainless steel insert which holds the CryoLoop. The Adjustable Mounted CryoLoop may be positioned several times. Note: Repeated manipulation will fatigue the sleeve which can lead to failure of the sleeve. The Adjustable Mounted CryoLoop is designed to work with the CrystalCap System components.
The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and stake it to the CrystalCap™ Magnetic or CrystalCap™ Copper Magnetic. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic.
Most data collection geometries prefer or require a 22 mm length between the base of the cap and the beam. For a 22 mm overall length using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT, snap the MicroTube at the second notch from the bottom, creating an 18 mm MicrozTube lenghth and secure to the CrystalCap using epoxy or similar adhesive. For a 22 mm over length using the CrystalCap Copper, CrystalCap Copper HT, CrystalCap ALS Copper HT snap the MicroTube at the fifth notch from the bottom (notch closest to the CryoLoop) and secure to the CrystalCap using epoxy or similar adhesive.
The HR5-902 Tool for Adjustable Mounted CryoLoop is not included with the Adjustable Mounted CryoLoop and must be purchased as a separated item.

Description
MembFac is a highly effective sparse matrix screen specifically designed as a preliminary screen for the crystallization of membrane proteins. MembFac is based upon the highly effective biased sparse matrix methodology. The MembFac screen matrix is optimized for the crystallization of membrane proteins.
MembFac contains 48 unique reagent formulations. With this set of 48 conditions, numerous chemicals and chemical combinations are utilized, allowing one to evaluate a large variety of potential crystallization conditions. MembFac covers a broad pH range between 4 and 9.
The Rationale
The basic rationale of MembFac is to perform a sparse matrix screen while changing the detergent dimension because detergents play an important factor in the crystallization of membrane proteins. A MembFac screen is to be completed for each detergent. Detergent screens are available separately.
The Method
The membrane protein of interest is first isolated in the detergent which gives the highest stability and activity. The protein concentration should be approximately 10 to 20 mg/ml and the detergent concentration should be only slightly above the CMC. The sample is then set against MembFac, using all 48 solutions plus the screening detergent(s) of choice. The screening detergent concentration should be approximately one to three times the CMC. Hence, for each detergent screened, one would utilize approximately 1 to 2 mg of sample.
The MembFac protocol was used to crystallize membrane proteins including SQR, fumerate: quinone oxireductase, LHII, and LHCII.
Crystal Screen Lite is a sparse matrix of trial crystallization reagent conditions based upon the Crystal Screen™.3 The primary screen variables are salt, pH, and precipitant (salts, polymers, volatile organics, and non-volatile organics).2Crystal Screen Lite differs from the original Crystal Screen kit in that the primary precipitant reagents are one-half the concentration of that used in the original Crystal Screen formulation. The secondary salts, ions, and buffers remain at the original Crystal Screen concentration. Reducing the primary concentration of the primary precipitant results in a screen which is “more gentle” on the sample and typically produces much less precipitate conditions than the original Crystal Screen.
MembFac contains 48 unique reagents, 10 ml each.
MembFac HT contains 1 ml each of all 48 reagents from MembFac and reagents 1-48 from Crystal Screen Lite in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

Description

Solubility & Stability Screen is designed to assist in the identification of solution conditions which promote protein solubility and stability, and minimize protein precipitation. Solubility & Stability Screen is a solubility screen, a stability screen, and may also be used as an additive screen in the presence of a crystallization reagent.
The Hampton Research Solubility and Stability Screen can evaluate protein solubility, stability and crystallization in the presence of 94 different chemical additives sampling 17 different classes of reagents plus two controls.
Protein solubility and stability are universally required in a wide range of applications, including general biochemical studies, the preparation of proteins in pharmaceuticals, structural biology and crystallization.1-11The preparation of a concentrated, soluble and stable protein sample can often be a difficult task as proteins often aggregate, precipitate or denature.
Thermofluor (also known as Differential Scanning Fluorimetry, DSF and Protein Thermal Shift) provides a rapid, convenient and effective means of identifying subsaturating solution conditions that may also correlate with protein heterogeneity and poor crystallization outcomes.12
Protein solubility and stability is affected by many different chemical factors including pH, buffer type, chemical additives and excipients. pH and buffer type are dominant protein solubility and stability variables and can be evaluated and optimized using the Hampton Research Slice pH kit HR2-070. Slice pH evaluates protein solubility, stability and crystallization versus 20 different buffers over the pH range 3.5-9.6. Chemical additives influencing protein solubility and stability can be evaluated using the Solubility & Stability Screen.
It is widely accepted that protein solubility and stability can be increased by the use of chemical additives.5,15Seventeen classes of reagents are sampled by the Solubility & Stability Screen and each of these classes has been reported as important in improving sample solubility and stability.2-11
The Solubility & Stability Screen is a set of 94 high purity reagents formulated in high purity water (NCCLS/ASTM Type 1+) at 25°C and are 0.22 micron sterile filtered. The 94 solubility and stability reagents are formulated at 2 to 10 times their recommended working concentration. The remaining two reagents are water and a negative (TCA) control. A water control demonstrates the effect of diluting sample as well as sample buffer concentration. TCA, the negative control, demonstrates total sample precipitation, loss of sample solubility and loss of sample stability. The effects of the Solubility & Stability reagents can be compared with this negative control to assist in the identification of reagents promoting sample solubility and stability. 500 microliters of each reagent is supplied in a sterile 96 well polypropylene Deep Well block. The Solubility & Stability Screen reagents are compatible with the sitting or hanging drop vapor diffusion, microbatch, free interface diffusion, sandwich drop vapor diffusion, and dialysis crystallization methods utilizing water soluble reagents.

The Adjustable Mounted CryoLoop is a 20 micron diameter synthetic loop mounted inside a malleable stainless steel sleeve, which in turn, is mounted inside the EasySnap MicroTube™.
Using a specially designed L-shaped tool (HR5-902) with a positioning notch, one can manipulate the angle and orientation of the CryoLoop by bending and adjusting the angle of the malleable stainless steel insert which holds the CryoLoop. The Adjustable Mounted CryoLoop may be positioned several times. Note: Repeated manipulation will fatigue the sleeve which can lead to failure of the sleeve. The Adjustable Mounted CryoLoop is designed to work with the CrystalCap System components.
The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and stake it to the CrystalCap™ Magnetic or CrystalCap™ Copper Magnetic. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic.
Most data collection geometries prefer or require a 22 mm length between the base of the cap and the beam. For a 22 mm overall length using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT, snap the MicroTube at the second notch from the bottom, creating an 18 mm MicrozTube lenghth and secure to the CrystalCap using epoxy or similar adhesive. For a 22 mm over length using the CrystalCap Copper, CrystalCap Copper HT, CrystalCap ALS Copper HT snap the MicroTube at the fifth notch from the bottom (notch closest to the CryoLoop) and secure to the CrystalCap using epoxy or similar adhesive.
The HR5-902 Tool for Adjustable Mounted CryoLoop is not included with the Adjustable Mounted CryoLoop and must be purchased as a separated item.

Description
Art Robbins Instruments has developed the ideal family of plates for crystallography applications: the Intelli-Plate. All versions of the Intelli-Plate have the SBS microplate footprint and standard well spacing and are ideal for manual or automated processing.
The Intelli-Plate 96-2 Low Profile (Art Robbins 102-0001-10 Hampton Research HR3-116 and HR3-117) is a low profile version of the Intelli-Plate 96-2 LVR (Low Volume Reservoir). Reservoir volume: 100 µl max. Drop well volume: 4 µl and 10 µl max. UV transmissible and low birefringence.
The CrystalMation Intelli-Plate 96-3 low-profile crystallization plate (Art Robbins 102-0001-13 Hampton Research HR3-118 and HR3-119) is a low profile version of the Intelli-Plate 96-3 LVR (Low Volume Reservoir). The plate is designed for sitting drop vapor diffusion crystallization experiments. It is constructed from optically clear, UV-transmissible, chemically resistant plastic with superior low birefringence. The low-profile construction allows for higher density in plate storage and imaging systems, maximizing your investment and valuable space. The plate is designed to be a substantial improvement in existing low-profile plates, allowing for superior sealing due to thicker well design and a flat sealing surface. It has been built to the SBS (Society for Biomolecular Screening) standard dimensions with 8 vertical wells along the left side of the plate (A-H) and 12 horizontal wells along the top of the plate (1-12). It is compatible with automated instrumentation including the CrystalMation line of instruments from Rigaku. The plate features three identical sized sample drop wells per reservoir. The wells are concave depressions along the left side (Y-axis) of the plate and are located on the ledge above the adjacent, flat bottom reagent reservoir. Each well features a round bottom for easy crystal harvesting and can hold up to 1 µl of sample. The multiple well design allows for combinatorial experiments, complex co-crystallization experiments for ligand screening, or for drop concentration variation. The reagent reservoir is typically filled with 50 to 70 µl of reagent. Reservoir volume: 100 µl max. Drop well volume: 1 µl max. UV transmissible and low birefringence.
The Intelli-Plate 96-2 LVR (Art Robbins 102-0001-00 Hampton Research HR3-143 and HR3-145) is a Low Volume Reservoir version of the original Intelli-Plate. Reservoir volume: 100 µl max. Drop well volume: 1 µl max. UV transmissible and low birefringence.
The Intelli-Plate 96-3 LVR (Art Robbins 102-0001-03 Hampton Research HR3-183 and HR3-185) is a Low Volume Reservoir, 3 drop well version of the Intelli-Plate. Reservoir volume: 100 µl max. Typical reservoir volume 50 µl. Drop well volume: 1 µl max. UV transmissible and low birefringence.
The Intelli-Plate 96-2 Original crystallization plate (Art Robbins 102-0011-00 Hampton Research HR3-297 and HR3-299) is an optically clear plate for sitting drop vapor diffusion crystallization. All wells have standard 9 mm spacing to conform to SBS standards with 8 vertical wells along the left side of the plate (A-H) and 12 horizontal wells along the top of the plate (1-12). This plate features two locations for sample per reservoir. The sample drop locations are located along the left side of the reagent reservoir, along the Y-axis of the plate. The sample wells are concave depressions on the ledge above the adjacent, flat bottom reagent reservoir. One sample well is located above the second sample well. The top sample well can hold 10 µl or less of sample. The lower sample well can hold 4 µl or less of sample. The reagent reservoir is typically filled with 100 µl of reagent and is capable of holding up to 300 µl of reagent. The sidewalls separating adjacent wells or reservoirs are 0.9 and 1.0 mm thick in order to offer a larger area for sealing the plate and a separation of the reservoirs. This plate is rigid, with virtually no torsional flex and is designed for either manual or automated pipetting. UV transmissible and low birefringence.
The Intelli-Plate Flat Shelf (Art Robbins 102-0001-01 Hampton Research HR8-171 and HR8-172) crystallization plate is a flat drop shelf version of the original Intelli-Plate. Reservoir volume: 300 µl max. No drop well. UV transmissible and low birefringence.
The Intelli-Plate 96-2 Shallow Well (Art Robbins 102-0001-20 Hampton Research HR3-163 and HR3-164) has two identically sized 2 µL reaction wells and a 140 µL screen reservoir. Each of the two identical well features a round bottom shallow well design for easy crystal harvesting and is arranged in an 8 x 12 array. This plate has low birefringence and is UV compatible. This plate is also available in a low profile height (Art Robbins 102-0001-21).
The plates can be sealed using Crystal Clear Sealing Film (HR3-609), 3 inch wide Crystal Clear Sealing Tape (HR4-506) or ClearSeal Film™ (HR4-521).
The height of Intelli-Plate is 0.560 inches. The height of Intelli-Plate Low Profile is 0.315 inches (8.001 mm).

Description
Index is designed as a 96 reagent crystallization screen that combines the strategies of the grid, sparse matrix, and incomplete factorial screening with traditional, contemporary, and new crystallization reagent systems into a highly effective and efficient format.
Index, as the name implies, efficiently samples a series of specially formulated reagent zones to identify which reagent class or classes and pH are effective in producing crystals or limiting sample solubility. Results from Index can be used to design optimization experiments and to identify follow on screens by reagent class. For example, positive results with salt based reagents in Index may be followed up with further screening using SaltRx or Grid Screen Salt HT. Success with polymer based reagents in Index may be followed up with further screening using PEGRx or PEG/Ion.
Index utilizes a broad, yet refined portfolio of crystallization reagent systems. These include the following: (1) traditional salts such as Ammonium sulfate and Sodium chloride versus pH; (2) neutralized organic acids such as Sodium malonate and Tacsimate; (3) High salt concentration mixed with low polymer concentration as well as high polymer concentration mixed with low salt concentration and; (4) Low ionic strength using polymers such as PEG, MPD, Pentaerythritols versus pH. These reagent systems are formulated across a sparse matrix and incomplete factorial of concentration ranges, sampling a pH range of 3 to 9.
Index contains 96 unique reagents, 10 ml each.
Index HT contains 96 unique reagents in a single Deep Well block format.
Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.
