KEY FEATURES & APPLICATIONS: ? Water-soluble ? Has primary amine-reactive N-hydroxysulfosuccinimide (Sulfo-NHS) esters at both ends ? Contains cleavable, 8-atom (12 A?) spacer arm ? The disulfide bond in the spacer arm is cleavable with reducing agents such as DTT, TCEP, etc. ? DTSSP crosslinker is membrane-impermeable, thus enabling cell-surface crosslinking without interfering with intercellular proteins. MW: 608.51. Purity ≥80% by NMR
