用固相ｐＨ梯度等电聚焦技术及免疫固定技术对２０１名北京地区无关汉族群体的人血清Ｇｃ蛋白亚型进行了分型鉴定及基因频率的调查．Ｇｃ￣（ｌＦ）为０．３６９８．Ｇｃ￣（ｌｓ）为０．２８１２．Ｇｃ￣２为０．３４９０．观察值与期望值吻合良好（Σｘ￣２＝１．０５７，Ｐ＞０．７０） 201 human plasma Gc protein subtypes unrelated to the Han population in Beijing were genotyped and the gene frequencies were investigated by solid phase pH gradient isoelectric focusing and immunofixation techniques. Gc ~ (lF) is 0.3698. Gc ~ (ls) is 0.2812. Gc ~ 2 is 0.3490. The observed value was in good agreement with the expected value (Σx = 2 = 1.057, P> 0.70)
