ABSTRACT
Objective To study the preparation of hepatitis C viruses (HCV) genotyping oligochip and its application in the detection of 76 hepatitis C patients.Methods Oligonucleotide probes and primers were designed in the 5’noncoding region and core region of HCV. The HCV typing chip was prepared by spotting the modified probes onto nylon membrane. Products of the second PCR were labeled with Dig-dUTP. Furthermore, 6 PCR products were sequenced.Results Using the chip,15 subtypes in 11 types of HCV were analyzed.Results of hybridization indicates that 76 hepatitis C patients were all positive and 20 health people were negative.Among 76 patients, 64 cases were 1b type, 11 cases were 2a type and 1 case was 3a type. Mix infection was not found. The results obtained by sequencing 6 samples and chip arraying were the same.Conclusion The HCV genotyping chip could be used in detecting serum HCV RNA and analyzing its genotypes.
