Comparative study on detection methods of mutations in hepatitis B virus precore and basic core promoter / 中华检验医学杂志

ABSTRACT

0.05). The sequence of five clones from one serum which was identified precore mutation by mPCR-RFLP were all A1896 mutant strains.Another serum identified mixture infection by mPCR-RFLP , one clone was A1896 mutant strain and four were G1896 wild strains.The results of mPCR-RFLP were verified by cloning.Conclusions Comparison with sequencing, the mPCR-RFLP method is simple,accurate and can be used in large-scale surveys and clinical research.
