Biotin-bisamido-SS-NHS is a cleavable reagent which can efficiently introduce a biotin moiety to amine-containing biomolecules. The cross-bridge and extended spacer arm are helpful in minimizing steric hindrance involved with the binding to avidin or streptavidin probes. This biotin compound is membrane-permeable and useful for intracellular labeling. 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.
