Description

Bifunctional 4-Arm PEG reagents have two functional groups Acid and Amine at specific ratio of 1:3, 2:2, 3:1. The amine and acid functionality are for reaction with NHS ester and peptide coupling or conjugation chemistry. Bifunctional PEG synthesized via our proprietary chemistry to produce precisely predetermined ratios of the two functionality. These reagents provide extended application for multi-arm PEG as heterobifunctional crosslinkers.
