Application

Biotin-PEG4-alkyne may be used for the modification of 4-azidophenylalanine (AzPhe) silk fibroin via bioorthogonal azide–alkyne cycloaddition reaction for developing photopatternable protein material.
Biotinylation reagent for labeling azide containing molecules or biomolecules using copper-catalyzed 1,3 dipolar cycloaddition click chemistry. The alkyne group reacts with azides to form a stable triazole linkage, facilitating the introduction of biotin into your azide modified system of interest.
