Additive screen is a library of reagents that can affect the solubility and crystallization of biological macromolecules, including both soluble and membrane proteins. These reagents can perturb and manipulate sample-sample and sample-solvent interactions, as well as perturb water structure which can alter and improve both the solubility and crystallization of a sample.
Additives can stabilize or engender conformity by specific interaction with the macromolecules. There are numerous reports of the use of additives to improve the quality and size of macromolecular crystals. Additive screen reagent classifications include multivalent, salt, amino acid, dissociating agent, linker, polyamine, osmolyte, chaotrope, co-factor, reducing agent, chelating agent, polymer, carbohydrate, non-detergent, amphiphile, detergent, non-volatile organic and volatile organic.
