Galactose PEG Succinimidyl Carboxymethyl Ester


Made to order. PEG products with additional MW may be made to order, please contact us for details


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.

JenKem Technology offers Galactose PEG Succinimidyl Carboxymethyl Ester with MW 35000 (GALA-SCM-35K), in 1g and 10g packing sizes. Different MW of Galactose PEG Succinimidyl Carboxymethyl Ester products may be available by custom synthesis, please email us at for details on custom PEGs. JenKem Technology provides repackaging services for an additional fee, please contact us if you require a different package size than our catalog selection.

Bulk PEGs and GMP grade PEGs are made-to-order. Please contact us for bulk pricing.
