Hampton 蛋白结晶试剂–Crystal Screen
Crystal Screen • Crystal Screen 2 • Crystal Screen HT

Applications
 Primary screen for proteins, soluble peptides, nucleic acids, & water soluble small molecules
 Sparse matrix additive screen

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.
Crystal Screen HT contains 1 ml each of reagents 1-48 from Crystal Screen and all 48 reagents from Crystal Screen 2 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.

Wizard Tube 
The Wizard™ Classic line of random sparse matrix screens is designed to increase your probability of producing crystals during the coarse screening phase when crystallizing biological macromolecules (proteins, nucleic acids, peptides, and combinations thereof).
The Wizard Classic reagents are proven to be a highly effective starting point in the screening of biological macromolecules. The Wizard Classic formulations include a large range of crystallants, buffers, and salts covering a broad range of crystallization space at pH levels from pH 4.5 to pH 10.5.Choose from Wizard Classic 1, 2, 3, or 4 non-overlapping formulations in matrix blocks or tubes.

Wizard Cubic LCP
The tools in the Wizard Cubic LCP (lipidic cubic phase) Kit enable researchers to prepare LCP-type crystallizations by hand. Ideal for low-protein experiments: effective protein volume for a single crystallization experiment is about 80 nanoliters. Wizard Cubic LCP Kit tools work especially well when traditional methods have failed to yield crystals. Lipidic cubic phase has worked well for the crystallization of 7TM membrane proteins (proteins with seven transmembrane helices). Four out of six GPCRs (G-protein coupled receptors), an important membrane protein class, and several microbial 7TM proteins have been crystallized using the LCP approach.

CRYO (I、II)
The Wizard Cryo™ line of random sparse matrix screens is designed for scientists who want to avoid the additional step of optimizing a cryoprotectant condition. Every Wizard Cryo formulation flash-freezes to a clear, amorphous glass in liquid nitrogen or in a cryo-stream at 100K. Crystals can be frozen directly from their growth drops, avoiding the additional step of pre-equilibration with an artificial cryo-condition that can damage the crystal. Eleven different cryocrystallants and sparing use of glycerol ensures a broad sampling of possible cryo conditions. Choose from Wizard Cryo 1 or 2 formulations in tubes or Wizard Cryo 1 and 2 together in a 96-well matrix block.

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.
The following slides are UV transmissable (>85%):

Hampton蛋白质结晶捞针（结晶环）18 mm Mounted CryoLoop™

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.

Hampton  MembFac • Crystal Screen Lite • MembFac HT

Features
  Membrane protein sparse matrix screens
  Sparse matrix formula efficiently samples salts, polymers, organics and pH
  pH range 4.6 – 8.5
  Formulated for use with detergents
   Tube or Deep Well block format
   Crystal Screen Lite features a lower ionic strength than the original Crystal Screen

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.
