| Abstract: | In this experiment,an efficient method of recovering low-molecular weight DNA fragments from agarose gel was reported.Three methods(the modified freezing-thawing method,the freezing-thawing method and the Agarose Gel DNA Purification Kit made by TAKARA)were used to extract and purify 155bp DNA fragments.Results were compared by agarose gel electrophoresis.At last,DNA fragments was quantitated by the method of ultraviolet absorption.Results showed:The modified method is an easy,efficient and cheap one for recovering low-molecular-weight DNA fragments. |
