Electrophoretic analysis in the presence of 33% glycerol of purified myosin from normal human muscle shows three distinct protein bands which are identified as type 1, 2B, and 2A myosin heavy chain (MHC) isoforms by affinity-purified polyclonal antibodies. Analysis of MHC of single human muscle fibres shows that human muscles contain a large population of fibres showing the coexistence of type 2A and 2B MHC.
在含有33%甘油的条件下，对来自正常人体肌肉的纯化肌球蛋白进行电泳分析，结果显示有三条不同的蛋白带，通过亲和纯化的多克隆抗体将其鉴定为1型、2B型和2A型肌球蛋白重链（MHC）异构体。对单根人体肌纤维的MHC分析表明，人体肌肉中含有大量同时存在2A型和2B型MHC的肌纤维。
