WebThe most popular of these reagents are NHS-ester/maleimide compounds, such as Sulfo-SMCC and its pegylated analogs, SM(PEG) n. Chemical structure of Sulfosuccinimidyl-4-(N-maleimidomethyl)cyclohexane-1-carboxylate (Sulfo-SMCC). It is a non-cleavable and membrane impermeable crosslinker. WebPEG NHS ester linkers have been widely usded for crosslinking or labeling peptides and proteins. They readily react with primary amine groups at the N-terminus of polypeptide chains and lysine amino groups. These primary amines exist predominantly on the outside surfaces of protein and are readily accessible to NHS ester for bioconjugations. In ...
