Comparision of their maps, 40 different spots were digested in gel with TPCK-trypsin and measured with MALDI TOF MS, and 20 protein were identified, which may help to search mechanism of the development of lateral root.

• 分析其不同部位的双向电泳图谱的蛋白质表达差异,应用胰蛋白酶胶内酶解及基质辅助激光解吸/电离飞行时间质谱(MALDI-TOFMS)的肽质指纹技术对40个差异表达蛋白质进行鉴定,最终鉴定出20个蛋白,从而为侧根发生机理的研究提供科学依据。
