Result The background noise of bidirectional electrophoresis map of protein extracted by TCAJA method was greater, its clarity was poor, its horizontal striations were more and there were tinny spots with irregular shape appeared on it. The variegated spots had difference from the normal protein spots, they formed high coverage and shading on the other protein spots and affected the accurate expression of map information. The background noise of bidirectional electrophoresis map of protein extracted by Trizol method was little, its horizontal striations and non-protein impurities were less, there was no shading phenomenon strong spots and mere protein spots, so it provided abundant information for quantitative and qualitative analyses on the proteome from buffalo grass seeds, Compared with TCA/A precipitation.

结果］TCA/A法提取的蛋白质双向电泳图谱背景噪音大，清晰度差，横向条纹较多，图谱上呈现多个形状不规则的斑点，杂色与正常蛋白质点有区别，对其他蛋白质点构成高度及盖和遮进，影响图谱信息的准确表达；Trizol法所提取的蛋白质样品，其双向电泳图谱背景嗓音小，横向条纹少，非蛋白类杂质少，无斑点间的这进现象，蛋白质点数量增多，为野牛草种于蛋白质组定量、定性分析提供了丰富的信息。
