Description: The PURExpress® Disulfide Bond Enhancer (PDBE) is a proprietary blend of proteins and buffer components designed to correctly fold target proteins with multiple disulfide bonds produced in PURExpress reactions. Added at the beginning of a reaction, the components promote a proper disulfide bond pattern by assisting with the oxidation of cysteine thiols and correcting mis-oxidized substrates. These enhancements can increase the yield of soluble and functionally active protein.
Reagents Supplied:
PURExpress Disulfide Bond Enhancer 1
PURExpress Disulfide Bond Enhancer 2
Reaction Conditions:
Add 1 µl of each component to a PURExpress reaction (as part of the user-added 7.5 µl volume for templates and additives) and incubate reaction at 37°C for at least 2 hours.
Applications:
Formation of properly folded proteins containing multiple disulfide bonds when produced by PURExpress.
Incubate at 37°C.
