Abstract
A highly specific and broadly reactive monoclonal antibody against hepatitis B virus X (HBx) protein was developed that detected, in both immunoblotting and immunofluorescence, HBx proteins of seven of the eight currently known genotypes of HBV, which were overexpressed in cultured cells. Evaluation of HBx expression levels in cultured hepatocytes using this monoclonal antibody showed that cells transiently and stably transfected with HBV genomes expressed far less HBx protein than cells transiently transfected with an HBx overexpression plasmid routinely used for studying HBx functions. The availability of such sensitive and broadly reactive monoclonal antibodies against HBx will enable more-quantitative studies of HBx functions.
