摘要:
The present invention provides an in vitro activity assay for human hepatitis B virus (HBV) DNA polymerase, which comprises using, as the 5′ oligonucleotide in PCR amplification of HBV DNA polymerase from a sample, an oligonucleotide into which has been incorporated the SP6 viral polymerase promoter, directly transcribing and translating the PCR products in the presence of a radio-labelled agent and measuring the priming of the HBV DNA polymerase. The present invention also provides the use of such an assay to assay activity of various serum samples, to screen for inhibitors of the HBV DNA polymerase and to test and/or screen potential anti-HBV drugs for their ability to inhibit DNA priming activity of human HBV DNA polymerase.

This invention provides an isolated strain of Hepatitis B virus designated Human Hepatitis B Virus Surface Antigen-‘S’-133 Oon Strain (Methionine to Threonine) which constituent viral genome is deposited under Accession Nos. P97121501, P97121502 and P97121503 with the European Collection of Cell Culture on 15th Dec. 1997. This invention also provides an isolated nucleic acid encoding a polypeptide which is a mutant major surface antigen of a strain of hepatitis B virus, such polypeptide having an amino acid sequence which differs from the amino acid sequence of a major surface antigen of a wild type hepatitis B virus in that the amino acid at position number 133 of such polypeptide is a threonine rather than a methionine. This invention also provides an isolated nucleic acid which encodes a peptide, wherein the peptide is encoded by a nucleic acid molecule comprising nucleotides 527 through 595 of SEQ. I.D. No. 1 and the purified peptide. This invention also provides various methods of using the disclosed isolated nucleic acid and peptides.
