摘    要:目的]纯化猪血免疫球蛋白IgG,并测定其轻链与重链的分子量。方法]采用分步硫酸铵盐析法粗提猪血浆中的免疫球蛋白G,透析袋脱盐后用DEAE-SephadexAS0对IgG进行纯化,对纯化后的免疫球蛋白进行SDS-PAGE电泳,采用AlphaEaseFC凝胶分析软件对凝胶图像进行分析。结果]3份样品中免疫球蛋白的浓度分别为2.712、2.679、2.489mg/ml;电泳后每泳道均出现2条蛋白带,说明所提免疫球蛋白的纯度较高;2条蛋白带分别为IgG的重链(H链)与轻链(L链),与标准蛋白Marker进行比较可知,H链的分子量约为57KDa,L链的分子量约为26KDa。结论]得到了高纯度的猪IgG,并进一步确定了IgG轻链与重链的分子量。

关 键 词:猪血浆  免疫球蛋白  分子量
