The purity and quality of DNA obtained by this method is satisfying. The ratio of OD260 to OD280 is over 1.7. These genomic DNA are then amplified by PCR with two oligoneclotide primers synthesised to obtain partial nucleotide sequences of trypsin gene.是什么意思_The purity and quality of DNA obtained by this method is satisfying.
