WebAmine-reactive crosslinker reactive groups. The simplest, most common and versatile techniques for crosslinking or labeling peptides and proteins such as antibodies involve the use of chemical groups that react with primary amines (–NH2). Primary amines exist at the N-terminus of each polypeptide chain and in the side-chain of lysine (Lys, K ... Web8. EDC solution (1-Ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride) 9.
