DPDPB (1,4-Di [3’-(2’-pyridyldithio)propionamido] Butane)


Cat. No.: 10534 Categories: ,


General Description

DPDPB is a sulfhydryl reactive homobifunctional reagent with a spacer arm of 19.9 Å. It reacts with sulfhydryls to form a mixed disulfide, which can be readily cleaved in presence of a reducing agent. It functions via cysteine crosslinking and can be used to study protein structural analysis, protein modification, proteomics and homobifunctional cross-linking reagents.
