DESCRIPTION

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 producing crystals or limiting sample solubility. Results from Index can be used to design optimization experiments and to identify follow on screens by reagent class. For example, positive results with salt based reagents in Index may be followed up with further screening using SaltRx or Grid Screen Salt HT. Success with polymer based reagents in Index may be followed up with further screening using PEGRx or PEG/Ion.

Index utilizes a broad, yet refined portfolio of crystallization reagent systems. These include the following: (1) traditional salts such as Ammonium sulfate and Sodium chloride versus pH; (2) neutralized organic acids such as Sodium malonate and Tacsimate; (3) High salt concentration mixed with low polymer concentration as well as high polymer concentration mixed with low salt concentration and; (4) Low ionic strength using polymers such as PEG, MPD, Pentaerythritols versus pH. These reagent systems are formulated across a sparse matrix and incomplete factorial of concentration ranges, sampling a pH range of 3 to 9.
