Biotin-PEG-Alk (MW 600)

Biotin-PEG-Alk (MW 600) is a biotin-labeled, alkyne-functionalized polyethylene glycol used as a click chemistry reagent for protein, peptide, and oligonucleotide modification [1]. Featuring an alkyne group, it is intended for copper-catalyzed azide-alkyne cycloaddition (CuAAc) with azide-containing molecules.
