Abstract
HCV RNA positive serum was first selected by RT PCR test kit from several anti HCV positive sera obtained from Xi’an.HCV RNA extracted from the elected sera was converted to cDNA by reverse transcription with random primer.Half nested PCR was performed.The amplified product was 852 bp.The purified PCR product was digested by restriction endonucleases and then ligated to epressio vector pET 22b\++.Its nucleotide sequence was determined by dideoxy chain termination method.A comparison of the sequence with several isolates reported previously showed that the sequence belonged to HCV type Ⅱ.
