Azide-SS-biotin is a cleavable biotinylation reagent for labeling alkyne-containing biomolecules using click chemistry. The azide group reacts with alkynes, DBCO or BCN reagent to form a stable triazole linkage. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.
