Product Description	N-(Azido-PEG4)-N-bis(PEG4-NHS ester) is a branched PEG derivative with two NHS ester groups and a terminal azide. The azide groups enable PEGylation via Click Chemistry. The NHS ester can be used to label the primary amines (-NH2) of proteins, amine-modified oligonucleotides, and other amine-containing molecules. The PEG spacer allows for enhanced hydrophilic properties.
