一般描述
三（羟甲基）甲基甘氨酸是一种带电离子的生物缓冲剂，通常用于酶测定、电泳和细胞培养研究。与甘氨酸相比，它具有更高的负电荷，这使得它能够更快地迁移。三（羟甲基）甲基甘氨酸′的高离子强度能够引起更多的离子迁移和更少的蛋白质迁移，从而在低丙烯酰胺凝胶中分离低分子量蛋白质。已经观察到，通过电泳，三（羟甲基）甲基甘氨酸在1至100 kDa蛋白质分离中的有效性。根据一项研究，在使用萤火虫荧光素酶进行ATP测定时，25 mmol/L的三（羟甲基）甲基甘氨酸缓冲液是经过测试的其他十种缓冲液中表现最有效。此外，三（羟甲基）甲基甘氨酸还可用于毛细管区带电泳、高效液相色谱和离子交换色谱。
应用
三（羟甲基）甲基甘氨酸作为一种多功能缓冲剂，适用于在低百分比的丙烯酰胺凝胶中分离低分子量的蛋白质，已经证明使用萤火虫荧光素酶进行ATP测定的有效性，并在研究辐射引起的膜损伤时表现出清除羟自由基的潜力。此外，它在分离和纯化参与特定mRNA翻译并含有特定肽-tRNA分子的核糖体中发挥了作用。.三（羟甲基）甲基甘氨酸还被用于合成RNA寡核苷酸和制备高密度DNA微阵列，从而能够通过光刻术法探索核酸·配体相互作用和文库构建的机制。

Electrophoretic separations of proteins are widely used in proteomic analyses, and rely heavily on SDS electrophoresis. This mode of separation is almost exclusively used when a single dimension separation is performed, and generally represents the second dimension of two-dimensional separations.
