- Description
N-(NHS ester-PEG3)-N-bis(PEG3-Mal) is a branched, 3-arm PEG reagent bearing one NHS ester and two maleimide groups. The NHS ester enables labeling of primary amines (-NH2) on proteins, amine-modified oligonucleotides, and other amine-containing molecules.
The maleimide groups react specifically with sulfhydryl groups at pH between 6.5 and 7.5 to produce stable thioether linkages. This combination provides amine- and thiol-reactive functionality within a single branched PEG reagent. Its molecular formula is C44H66N6O20, with a molecular weight of 999 and a specified purity of 95%.
