摘要
目的:用聚合酶链反应(PCR)法扩增丝状真菌中脱氧核糖核酸(DNA)片段。方法:将菌丝液氮研磨成粉状后溶于三羟甲基氨甲烷缓冲液(TE),煮沸15～20min后,用上清做模板扩增DNA片段,然后将PCR产物作琼脂糖电泳,把含有目的片段的胶切下后溶于TE,做第2次PCR的模板,PCR后琼脂糖凝胶电泳。结果:获得大量目的DNA片段。结论:此方法从丝状真菌中扩增DNA片段,是一种既经济又方便可行的方法,大大提高了工作效率,其效果显著。
Objective:Using PCR to amplify filamentous fungi DNA fragments. Methods:Pour some liquid nitrogen to the hypha and grind them to powder. Then add some TE buffer and boil them for 15-20 minutes. Take a little supernatant as PCR template. After PCR do agarose gel electrophoresis. Collect the gel containing the objective fragment and add some TE. Take a little supernatant as PCR template (again.) After PCR, do agorose gel electrophoresis again. Results:We obtained a great deal of objective DNA. Conclusion:Amplifying filamentous fungi DNA fragment by this way, we can save time and money. We can also improve our work efficiently.
