Biotin-bisamido-SS-NHS

Biotin-bisamido-SS-NHS

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.
