Studies on Monoclonal Antibodies to Hepatitis A Virus
Abstract: Three strain hybridomas (AG3, AD2, AE8) were developed by cell fusion technique. They secreted stably MeAbs against HAV with the titer of 1: 128000—1: 1024000 in ascites fluid by ELISA. All of these McAbs are of positive reaction on HAV derived from patient s stools and cell culture, and this reaction can be inhibited by human anti HAV positive sera. The results of cell neutralization test and cross-blocking ELISA show that AE8 McAb is able to neutralize HAV infectivity, and that these McAbs recognize diffe...
