电泳的应用清单



电力在生物过程中的作用与其在技术中的作用一样重要,并且已通过许多微妙而有趣的方式被用于科学用途。电泳是生物化学中广泛使用的一种技术,电泳是利用电流来操纵蛋白质分子,以用于一系列生物医学研究,诊断和制造目的。

DNA分析

电泳仪的一种主要用途是鉴定和研究DNA和DNA片段。DNA以其负电荷的一致性而著称,这意味着电流向DNA的任何部分施加大致相等的力。在这种压力下,DNA的较大和较小片段开始分离,因为它们受测试介质的摩擦力的影响会有所不同。当除去电流时,通常是琼脂糖凝胶或丙烯酰胺凝胶的介质会将分离的片段“冻结”在适当的位置,从而可以高分辨率对其进行检查。通常将染色剂(如溴化乙锭)添加到凝胶中,以使其更易于查看和解释结果。
