GC30018

SPDP (SPDP Crosslinker)

Also known as (2,5-dioxopyrrolidin-1-yl) 3-(pyridin-2-yldisulfanyl)propanoate

SPDP (SPDP Crosslinker) is a short-chain crosslinker that reacts with NHS ester groups and pyridyl disulfide reactive groups with cysteine thiols to form a cleavable (reducible) disulfide bond, thereby facilitating the coupling of amine and thiol groups
