title: Comparison of indicators for dane particles.
abstract: The Dane particle is-because of its characteristics--believed to be the complete hepatitis-B-virus. Sera containing high numbers of Dane particles were shown to be highly infectious. In the present study we related the HBeAg-, the HBsAg- and the anti-HBc titer to the level of DNA polymerase activity measured in 20 fold Dane particle concentrates. The data obtained indicate that the HBeAg concentration gives a semiquantitative estimate on the number of circulating Dane particles. Mean DNA polymerase activity was found to increase with HBsAg concentration and is therefore also of value-if determined in a HBeAg positive serum- for quantitation of Dane particles. The anti-HBc titer was found to be unrelated to the number of circulating Dane particles.
