Description

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. The selection, concentration, and pH of the salts were determined by data mining the BMCD1 and other crystallization databases, crystallization reports in the literature, and internal crystallization trials performed at Hampton Research. Based on this analysis, up to 35% of protein crystallizations involve salt as the primary crystallization reagent. SaltRx can be used as a primary crystallization screen when salt, ionic strength and pH are desired or suspected as appropriate crystallization variables. It is also useful as a secondary screen when salt only reagents/conditions from screens such as Index™, Crystal Screen™, and Grid Screen™ produce crystals and when further screening for additional salt conditions or optimization is desired. Since this screen does not contain volatile organics, it is compatible with microbatch, vapor diffusion, liquid and gel diffusion crystallization methods. SaltRx may also be used for dialysis crystallization in conjunction with Dialysis Buttons™.

The original SaltRx kit (HR2-108) contained 96 unique reagents, 10 ml each. This kit has been discontinued and converted into two 48 reagent based kits, SaltRx 1 and SaltRx 2, available separately, which when used together are identical to the original SaltRx.

SaltRx 1 contains 48 unique reagents, 10 ml each. SaltRx 1 contains reagents 1-48 of the original SaltRx 96 reagent kit.

Salt Rx 2 contains 48 unique reagents, 10 ml each. SaltRx 2 contains reagent 49-96 of the original SaltRx 96 reagent kit.

SaltRx HT contains the 96 SaltRx 1 and SaltRx 2 reagents in a single Deep Well block format.

Ready-to-use reagents are sterile filtered and formulated with ultra-pure Type 1 water, using the highest purity salts, polymers, organics and buffers. Individual reagents are available through the Hampton Research Custom Shop.

Measured pH range of kit is 4.1 to 9.0 at 25°C
Average measured pH of kit is 6.9 at 25°C
Median measured pH of kit is 7.3 at 25°C
Mode measured pH of kit is 7.4 at 25°C
