XP Screen An optimized JBScreen Basic complemented with the universal additive TEW as "glue" for protein molecules
JBScreen Classic The JBScreen Classic Kits 1-10 cover 240 (10 kits x 24 conditions each) of the most prominent conditions for protein crystallization. Their compositions result from mining of literature data of several thousands of crystallized proteins. JBScreen represents the selected statistically most successful buffers that yielded protein crystals suitable for X-ray diffraction.
JBScreen Basic Based on the classic sparse matrix crystallization screen published first by Jancarik and Kim in 1991, it contains 96 unique reagent mixtures for screening a wide range of pH and various salts and precipitants.
JBScreen LCP An LCP screen based on successfully crystallized integral membrane proteins in the Lipidic Cubic Phase.
