Sulfo-NHS-SS-biotin is a cleavable reagent useful for introducing a biotin moiety to proteins and cell surfaces containing primary amines. This biotin compound is membrane-impermeable due to its negatively charged, water soluble sulfonate group. The disulfide bond in this linker can be cleaved using reducing agents such as DTT, BME and TCEP to remove the biotin label. Reagent grade, for research purpose.
