title: [Identification of HBV genotype-specific tag sequences].
abstract: OBJECTIVE
  To identify the HBV genotype-specific tag sequence.
  
  
  METHODS
  The large S region sequences from 930 HBV genomes were aligned to identify the genotype-specific tag sequences. PCR was used to check the genotyping effect of these tags.
  
  
  RESULTS
  Two tag sequences, sequence between 149-169 and sequence between 461-483, were identified in the large S region. Using primers specific to these tag sequences, the genotype of HBV can be specifically identified.
  
  
  CONCLUSIONS
  These tag sequences can be used for HBV genotyping.
