N-Hydroxysulfosuccinimide Sodium Salt is a variant of N-Hydroxysuccinimide, derivatized with a sulfate group to confer hydrophilicity. N-Hydroxysulfosuccinimide Sodium Salt can be utilized similarly to NHS to activate carboxylic acids of interest to the more reactive succinimidyl esters for coupling, biotinylation, and conjμgation with fluorophores. Also used for crosslinking agents.多肽缩合剂，可形成稳定的活泼酯中间体。用于制备亲水性活泼酯，比如作为蛋白交联剂。 N-Hydroxysulfosuccinimide Sodium Salt is a variant of N-Hydroxysuccinimide, derivatized with a sulfate group to confer hydrophilicity.
