一般說明

三(2-羧乙基)膦(TCEP)能够在水溶液中高效裂解二硫键。与其他三烷基膦(三丁基膦)不同,TCEP溶于水且无味。它的毒性也比2-巯基乙醇更低。这些优点使其成为更好的还原剂。
属于三烷基膦类。

應用

三(2-羧乙基)膦(TCEP)可用于:
  • 还原合成肽中的半胱氨酸残基
  • RNA还原缓冲液 靶标顺序探测(SPOT)成像
  • 寡核苷酸还原
  • 用作线粒体分离期间的还原剂

三(2-羧乙基)膦(TCEP)可用于多种下游应用,包括SDS-PAGE、质谱、半胱氨酸特异性标签标记以及含半胱氨酸化合物的修饰。它可以防止蛋白质样品的氧化,这使其成为一种实用的缓冲成分以帮助保留酶活性。它已被用于谷胱甘肽的还原和测量。

生化/生理作用

三(2-羧乙基)膦盐酸溶液可还原二硫键,同时保持蛋白质中的其他官能团完整。
作为非硫醇还原剂,它不具有含巯基化合物固有的毒性。它能够破坏由单个二硫键连接的肉毒杆菌神经毒素B重链/轻链复合物,该复合物导致毒素的内吞并最终产生毒性。由于二硫键偶联亚基是许多毒素(如蓖麻毒素、蛇毒和所有BoNT血清型)的特有基团,因此,在毒素给药时可使用TCEP作为抢救预防措施。
