目的:使用核酸染料Genefinder检测琼脂糖凝胶中的核酸,通过比较预染样品法、胶内染色法和后染法三种染色方法的染色效果,了解该染料的染色特性,以期找到性能稳定,染色效果好的染色方法。方法:在琼脂糖凝胶电泳中,以不同的染色方法使用核酸染料Genefinder进行染色,对染色结果进行比较分析。结果:使用电泳后染色方法染色效果较好,胶内染色法次之,预染样品法效果最差。结论:核酸染料Genefinder会干扰DNA的迁移效率,因此,使用Genefinder进行电泳后染色是一种较好的染色方法。
Objective: To find out a high-efficiency and steady performance of staining nucleic acid with Genefinder in agarose gel electrophoresis.Method:Comparative analysis was performed on the staining effects corresponding with three different methods of Genefinder staining.Result:Staining nucleic acid with Genefinder after agarose gel electrophoresis has a satisfactory effect,while staining in agarose gel electrophoresis does worse and staining with preparative dye liquor has the worst effect.Conclusion:Probably Genefinder has an effect on the mobility of nucleic acid in agarose gel electrophoresis,therefore,a better way is to stain nucleic acid with Genefinder after the agarose gel electrophoresis.
