Bromo-PEG-NHS ester
NHS (PEG)n Bromide is a sulfhydryl-reactive and amine-reactive heterobifunctional crosslinker. The reagent’s NHS ester reacts with primary amines at pH 7-9 to form stable amide bonds, and the bromacetyl reacts with sulfhydryl groups at pH >7.5 to form stable thioether bonds. The reagent is useful for preparing cyclic peptides and peptide conjugates because the space maintains peptide-like character in the crosslinked species.
