JBScreen Buffer Kits are designed for convenient reproduction and optimization of crystallization conditions. The solutions can be used to reformulate conditions of the JBScreen family, e.g. JBScreen Classic, JBScreen Basic, JBScreen Cryo, and other commercially available crystallization screens.

Furthermore, JBScreen Buffer Kits can be employed for the straightforward preparation of custom screen solutions for the refinement and optimization of initial crystallization conditions. The JBScreen Buffer Kit formulations will help to save time preparing accurate and high-quality reagents for the reproducible production of single protein crystals.


The JBScreen Buffer Kits contain ready-made buffer solutions with preset pH values.

• JBScreen Buffer Kit Sodium Acetate, pH 3.5 – 5.6


• JBScreen Buffer Kit Sodium Citrate, pH 3.7 – 6.0


• JBScreen Buffer Kit MES, pH 5.6 – 6.7


• JBScreen Buffer Kit HEPES, pH 6.8 – 8.2


• JBScreen Buffer Kit Tris-HCl, pH 7.1 – 9.0
