DTSSP crosslinker reagent is a water-soluble crosslinker that contains amine-reactive NHS-ester ends around an 8-atom spacer arm, whose central disulfide bond can be cleaved with reducing agents. is ideal for aqueous conjugation reactions. DTSSP crosslinker can be used to crosslink extracellular and membrane proteins. If intracellular crosslinking is desired, then DSP, the water insoluble analog of DTSSP ,can be used for your research.
