Isolation,Purification and DNA Polymerase Activity Analysis of DI-IBV Repficatlve Complexe
Abstract: Duck hepatitis B virus re plicativc complexe~ (DHBV RCs)wcl~e isol~ted from DI-~V—infected duck liver by chromato~aphy thxou Bio--Oel A 5m followed crose gradient centrifugation.The feIathe endogenous DNA polymcra.se activity of the purified RCs was 100 tim es higher than that of the unchromatosraphed one,confirmed by detecting their DHBcAg with Dot-EIA method.
