Monoclonal Antibodies against Human Paramyxovirus Type 3 and against SV5 Virus: Preparation and Preliminary Characterization

Abstract

Monoclonal antibodies against the major glycoprotein (HN) and the nucleoprotein (NP) of paramyxovirus SV5 and human paramyxovirus (PF) type 3 have been obtained. Two different epitopes have been detected on the SV5 HN polypeptide, one being specific to SV5 and the other also cross-reacting with PF-2 HN polypeptide. Monoclonal antibody against SV5 NP polypeptide also reacted with PF-2 NP polypeptide. Similar epitopes showing both specific and group cross-reactions were detected with PF-3 HN and NP monoclonal antibodies against PF-3 and Sendai viruses. No cross-reactions were detected between these two groups of paramyxoviruses.
