N-(DBCO-PEG4)-N-Biotin-PEG4-NHS is a branched PEG linker with a biotin, a DBCO and NHS ester. It can be used fro bioconjugation with proteins and biotin labeling. The NHS ester readily conjugate with amine-bearing biomolecules to form a stable amide bond. The DBCO group easily react through click chemistry with azide-tagged biomolecules fast and in high yielding.
