一般描述

盐酸胍,又称氨基甲脒盐酸盐,是一种多用途化合物,由于其强大的混沌特性而广泛应用于细胞生物学和生物化学研究。它可以破坏蛋白质和核酸结构,使其在纯化蛋白质和核酸(特别是mRNA)方面很有价值。盐酸胍能使蛋白质展开,促进蛋白质的纯化和再折叠,并能在较高浓度下有效地溶解变性不溶性蛋白质。

在较低浓度下,胍盐酸盐具有促进变性蛋白质再折叠的有趣能力,有助于蛋白质变性研究。在RNA提取中,它作为一种强变性剂破坏细胞结构,并通过使RNA酶失活来确保提取RNA的完整性。总的来说,盐酸胍的变性和再变性特性使其成为各种细胞生物学应用的必要试剂,包括蛋白质纯化、核酸分离和蛋白质再折叠研究。

应用

盐酸胍被用于:
  • 均质分解脑组织
  • 制备用于Ni-琼脂糖蛋白结合,分离,丙酰化和用珠上消化最大化减少非特异性结合亲和树脂的孵育缓冲液
  • 制备用于从人体组织中提取水溶性蛋白的溶液/提取缓冲液

强效离液剂,用于蛋白质的变性以及后续复性。该强效变性剂可溶解不溶性或变性的蛋白质,如包涵体。可用作使蛋白质或酶复性为活性形式的第一步骤。可能还需要脲和二硫苏糖醇 (DTT)。

生化/生理作用

盐酸胍,一种高效的离散剂,参与RNA分离,球蛋白变性和蛋白质复性研究。这种变性剂适用于快速,一步法亲和纯化质谱(AP-MS)实验。

特点和优势

用于细胞生物学和生物化学研究的多功能表面活性剂
