DETAILS

Description (English)

Application
Thiolating reagent for primary amines; thiol can be deprotected under mild conditions. Typically, couples initially to a molecule containing primary amine by amide bond buffered at pH 7.5. Deprotection may be accomplished with 0.05 M hydroxylamine at neutral pH. Useful for preparation of enzyme immunoconjugates and hapten carrier molecule conjugates.
Other Notes
Note that the ester couples very efficiently to primary amines compared to other thiolating reagents. In addition, this reagent will neutralize original amine positive charge.

Description (简体中文)

Application
伯胺的硫醇化试剂；在温和条件下可使硫醇去保护。通常在 pH 为 7.5 时引发耦合反应，通过酰胺键生成含伯胺的分子。在中性 pH 时可与 0.05M 羟胺发生去保护反应。用于制备酶免疫交联剂和半抗原载体分子偶联物。
Other Notes
注意，与其他硫醇化试剂相比，对伯胺的酯偶合作用非常有效。此外，这种试剂可以中和伯胺的正电荷。
