Study on Different Extraction Methods of Gomphocerus Sibilants Genomic DNA

摘要

In the experiment, the grasshopper in Siberia is taken as the research objec. The comparison of the genomic DNA of dried and soaked in alcohol samples are extracted by the method of saturated NaCl, CTAB and SDS. Experimental results show that SDS method brings the total DNA, saturated Nacl law and CTAB extraction law of total DNA in specimens of the lower rate in most Agarose gel electrophoresis testing marked degradation. In addition, ethanol college system obtained by overall DNA specimens is higher in the rate and quality of than that of the dry specimens.
