Abstract

A new indirect method for fluorescence localization of proteins making use of the avidin-biotin complex is described. We have prepared both a biotin-modified rabbit heavy meromyosin (BHMM) and a biotin-modified antibody to a smooth muscle myosin. After fixation, cells can be treated with either BHMM, which binds to actin, or the biotinyl antibody, which binds to myosin. In a second step the cell are treated with a fluorescent derivative of avidin (Fl-avidin) which binds to the biotinyl proteins and thus indirectly reveals the location of the cellular action or myosin.

摘要

本文描述了一种利用抗生物素蛋白-生物素复合物进行蛋白质荧光定位的新间接方法。我们制备了生物素修饰的兔重酶解肌球蛋白(BHMM)和生物素修饰的平滑肌肌球蛋白抗体。固定后,细胞可用与肌动蛋白结合的BHMM或与肌球蛋白结合的生物素化抗体处理。第二步,用抗生物素蛋白的荧光衍生物(荧光抗生物素蛋白)处理细胞,该衍生物与生物素化蛋白结合,从而间接显示细胞肌动蛋白或肌球蛋白的位置。
