Hampton 蛋白结晶试剂–Crystal Screen

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.

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

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.

The Cryschem Plate is a 24 well sitting drop plate that is sealed with clear sealing tape. The polystyrene plate is supplied with a raised cover so the plate can also be sealed with vacuum grease and plain glass or plastic cover slides (22 mm diameter). The stackable, 24 well plates have distortion-free, flat bottom wells and a concave sitting drop post in the center of the well for concentric equilibration of the drop with the reagent. Each plate is individually sealed. The top of the plate and each of the 24 wells is a single, flat plane for smooth and easy seal application. Well spacing provides for a large seal area between wells to prevent cross contamination and evaporation.

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.

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.
