| Abstract: | The membrane filter technique was used to modify the traditional alkaline lysis method.Comparing the effect of extraction of the modified method with traditional alkaline lysis method and reagent kit method,the results showed that the plasmid DNA isolated and purified by this method had higher concentration than the other two methods,and had similar purity with the reagent kit method.Therefore the method was more suitable for the laboratory extraction and purification of plasmid DNA for a large scale. |
