细胞色素内是一种大分子生物活性物质。本文采用SDS聚丙烯酰胺凝胶电泳法对6批细胞色素内进行了分离和分子量测定,并做了凝胶电泳扫描,实验表明:所测各地产细胞色素内均存有杂蛋白及不均一性。材料和方法样品标准细胞色素内(新疆化学研究所试剂厂):新疆某厂,批号850214、840430;陕西某厂,批号840504;河南某厂,批号830109;天津某厂,批号831115、 Cytochrome is a macromolecular bioactive substance. In this paper, SDS polyacrylamide gel electrophoresis of six batches of cytochromes were isolated and molecular weight determination, and made a gel electrophoresis scan, the experiment shows that: the measured cytochromes in the local presence of heterogeneous protein and heterogeneity . Materials and Methods Sample Standard Cytochrome (Xinjiang Chemical Institute Reagent Factory): a factory in Xinjiang, batch number 850214,840430; a factory in Shaanxi Province, batch number 840504; a factory in Henan Province, batch number 830109; Tianjin factory, batch number 831115,
