PC Azido-PEG3-NHS carbonate ester is a photocleavable azido-PEG3 NHS carbonate linker for labeling primary amines on proteins, amine-modified oligonucleotides, and other amine-containing molecules. It combines an NHS carbonate reactive group with an azide handle and a photocleavable moiety to enable covalent labeling and light-triggered release. Supplied as a colorless to light-yellow oil for research use; follow manufacturer storage recommendations.
