Hampton Research, a US company, provides a comprehensive range of high-quality tools for crystallization, including crystallization screens, crystallization-grade reagents, crystallization plates, hardware and accessories, protein crystallization standards, and other supplies.
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.
Crystal Screen, Crystal Screen 2, and Crystal Screen HT are ready-to-use reagents that are sterile-filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers.
Determining initial and optimal cryoprotectant concentration is often a process of trial and error. One must find suitable cryoprotectant concentrations which stabilize the crystal while at the same time combine with the crystallization reagent to form an amorphous glass.
The Crystal Screen Cryo kits removes the guess work from determining the preliminary glycerol concentration required to mix with the crystallization reagent to form an amorphous glass. Crystal Screen Cryo reagents are formulated with the appropriate amount of glycerol required to form an amorphous glass with each unique reagent composition.
Hampton Research provides a comprehensive range of OptimizeTM Reagents which include crystallization-grade polymers, organics, salts, buffers, its Silver BulletsTM range of Individual Crystallization reagents for screening, optimization and production, as well as protein crystallization standards.
