PEG/Ion, developed by Hampton Research, is a crystallization screen designed to evaluate monodisperse, high purity Polyethylene glycol 3,350 and 48 unique salts representing a very complete range of anions and cations frequently used in the crystallization of biological macromolecules. The primary screening variables are PEG, ion type, ionic strength, and pH. More than 60% of the published crystallizations utilized PEG as a p…
SaltRx was developed by Hampton Research as a primary and secondary, salt and pH based crystallization screen for biological macromolecules. Salt is the only primary crystallization reagent (precipitant) utilized. Based on a design of 96 conditions, the screen evaluates a broad portfolio of crystallization salts of varying concentration and pH.SaltRx can be used as a primary crystallization screen when salt, ionic strength an…
Index is designed as a 96 reagent crystallization screen that combines the strategies of the grid, sparse matrix, and incomplete factorial screening with traditional, contemporary, and new crystallization reagent systems into a highly effective and efficient format. Index, as the name implies, efficiently samples a series of specially formulated reagent zones to identify which reagent class or classes and pH are effective in…
