Membrane Protein Crystallization Kits

The Creative Biostructure’s Basic Crystallization Kit for membrane proteins is a rapid and highly efficient screening tool to determine the best conditions for crystallization of hydrophobic macromolecules (primarily membrane proteins) in an empirical way. Based on known or published data for various proteins, broad ranges of buffers, pH, and precipitants in combination with a micelle-forming detergent are explored, using the sparse matrix method with a minimal amount of proteins.

The crystallization principle of the membrane protein crystallization kit is to shield the hydrophilic, charged parts of the macromolecules by the binding of the detergent to hydrophobic areas, which causes the solubility to decrease. Detergent mediated contacts then lead to precipitation or crystallization of the screening molecules.
