Galactose PEG Succinimidyl Carboxymethyl Ester with superior quality specification of ≥90% Substitution.
Galactose PEG Succinimidyl Carboxymethyl Ester is a JenKem Technology high quality amine reactive PEG product with a succinimidyl carboxymethyl ester reactive group and a targeting galactose group. Galactose PEG SCM reacts with amino group of lysine(s) at room temperature in under 1hr, at pH 7-8. The presence of the galactose monosaccharide increases significantly the selectivity of the PEGylation reaction.
