Comparison of Two Methods of Genomic DNA Extraction from Pork Liver

[Objective] The research aimed to compare the two extraction methods of genomic DNA from pork liver.[Method]kit method and chloroform/ isoamyl alcohol extraction method were adopted to extract genomic DNA from fresh pork liver.[Result] The results showed that the DNA extraction kit could obtain high purity genomic DNA with low density,and high concentration,good quality and relatively low cost by chloroform/ isoamyl alcohol method.[Conclusion] The chloroform/ isoamyl alcohol extraction of genomic DNA is a more effective method of promoting and using in molecular studies on fresh pork liver.
