Sulfo-NHS-Biotin (N-羟基磺酸基琥珀生物素)是一种胺反应性的生物素化试剂。最常见的胺反应性生物素化试剂可分为两种,N-羟基琥珀酰亚胺(NHS)酯和羧酸盐。通常,NHS酯-生物素化试剂包含反应性的NHS环结构,可以与蛋白或其它分子羰基上的胺反应,通过亲核攻击形成稳定的酰胺键,并释放NHS基团。由于NHS-biotin在水溶液中的不溶性,通过在NHS环结构上加入一个带负电荷的磺酸基,从而获得NHS-biotin的水溶性类似物sulfo-NHS-biotin。Sulfo-NHS-Biotin可以直接加入到反应性水溶液中,而不需要提前溶解在有机溶剂中。

• Protein labeling—biotinylate antibodies to facilitate immobilization, purification or detection using streptavidin resins or probes
• Cell surface labeling—do not penetrate the plasma membrane, biotinylates only surface proteins of whole cells
• Amine-reactive—reacts with primary amines (-NH2), such as lysine side-chains or the N-terminal-amine
• Solubility—charged sulfo-NHS group increases reagent water solubility compared to ordinary NHS-ester compounds
• Irreversible—forms permanent amide bonds; spacer arm cannot be cleaved
• Very short—spacer arm is 13.5 angstroms; it consists of the native biotin valeric acid group only
