Five different hybridoma clones secreting anti-HBeAg antibody were constructed by fusing cells of mouse myeloma line SP2/0 with splenocytes from BALB/c mice immunized with recombinant HBeAg. The monoclonal antibodies obtained were characterized immunologically and one was used to develop ELISA for detection of HBeAg and anti-HBeAg antibody. These monoclonal assays enabled the detection of 3 U HBeAg/ml and 1 U anti-HBeAg/ml with reference to standards of the Paul Ehrlich Institute, Frankfurt, F.R.G. Both assays compared well with a commercially available kit (Abbott Laboratory) and were used for detection of HBeAg and anti-HBeAg antibody in clinical serum samples.
