５个棉花材料的种子蛋白凝胶电泳分析结果表明，棉花种子中含有的脂类物质干扰分析，须脱脂处理方能获得准确结果；分离胶浓度对蛋白质分离效果有影响，本试验以１４％的分离胶浓度为棉花种子蛋白电泳的较适宜浓度；不同品种间，同一品种不同纯度问种子蛋白存在差异。这可以作为品种鉴定的一种手段。
The results of protein gel electrophoresis analysis showed that the lipids contained in the cotton seed interfere with the analysis and must be degreased to obtain accurate results. The concentration of the separating gel had an effect on the protein separation. In this experiment, 14% Separation gel concentration of cotton seed protein electrophoresis of the more appropriate concentration; different varieties, the same species asked different purity of the seed protein differences. This can be used as a means of identification of species.
