In order to reduce the influence of RNase on the subsequent experiment, the phenol-chloroform method was used to remove RNase. But it turned out that quantity of DNA was not sufficient enough to be extracted. We tried for several times but the results of the nucleic acid gel electrophoresis showed that we got nothing after the purification.
