JBS Products: Crystallization Screens
JBScreen Classic Kits 1-10 cover 240 (10 kits × 24 conditions each) of the most successful conditions for protein crystallization. Their compositions were obtained by examining the published crystallization conditions of thousands of proteins. JBScreen contains the statistically selected most successful buffers that yielded protein crystals suitable for X-ray diffraction.
Based on the classic sparse matrix crystallization screen first published by Jancarik and Kim in 1991, JBScreen Basic contains 96 unique reagent mixtures for screening a wide range of pH and various salts and precipitants.
Optimized for hydrophobic and membrane proteins.
A highly effective crystallization screen based on data analyses of published kinase structures.
For efficient screening of PEG 3350 and PEG 5000 MME versus 48 different salts.
An advanced cryo screen.
A highly specialized crystallization screen ideally suited for phosphatases. 96 conditions have been selected from a comprehensive survey of successfully crystallized phosphatases.
All screens are available either in kits of 24 - 10 ml vials or, for high-throughput screening (HTS), in 96-well deep well plates with 1.0 or 1.7 ml per well.
