Non-radioactive hepatitis B virus DNA probe for detection of HBV-DNA in serum.

Abstract：

:A diagnostic test has been developed to detect hepatitis B virus (HBV) DNA in human sera. This test involves a dot-blot technique in which non-radioactive nucleic acid labelled with 2-acetylaminofluorene (AAF) is used as probe. Two series of human sera from 228 blood donors and 113 HBsAg chronic carriers were tested by hybridization with the same DNA probe labelled either with AAF or with 32P. A correlation between the techniques was observed for 328 sera (96%), and using the non-radioactive test it was possible to detect 56 (86%) of the 65 HBV-DNA-positive patients. A comparative study of the HBeAg/anti-HBe status and the presence of HBV-DNA was carried out on the sera from 113 HBsAg chronic carriers, 65 of which were positive for HBeAg and 29 of which were positive for anti-HBe antibodies. With the AAF test, 44 of the HBeAg-positive sera were positive, while 5 of the anti-HBe-positive sera were positive. This study shows that, although this non-radioactive test is slightly less sensitive than the radioactive hybridization assay (RHA), it can be used for a survey of HBV carriers. Dissociation of the viral multiplication and the HBe/anti-HBe status was identified with the AAF test as well as with the RHA. It would therefore appear that the AAF test described here may be used for the extensive survey of HBV multiplication.
