随着科学技术的发展，蛋白质凝胶电泳技术以其简便、快捷、准确的特点逐渐代替了常规的玉米种子纯度鉴定方法，并被种子检验部门广泛采用。石家庄市种子监督检验站于１９９０年开始利用蛋白质凝胶电泳技术对玉米种子纯度指标进行检测，近年来共检测玉米种子样品１０００余个。 With the development of science and technology, the protein gel electrophoresis technology gradually replaces the conventional method of purity identification of maize seeds by its simple, quick and accurate characteristics and is widely used by the seed testing department. Shijiazhuang City Seed Supervision and Inspection Station in 1990 began using protein gel electrophoresis of maize seed purity indicators were detected in recent years, a total of more than 1,000 maize seed samples were detected.
