title: Parainfluenza virus type 2 haemagglutinin-neuraminidase glycoprotein characterized with monoclonal antibodies.
abstract: Thirteen monoclonal antibodies (MAbs) were prepared against human parainfluenza virus type 2 (PIV2). These MAbs reacted with the haemagglutinin-neuraminidase glycoprotein with an Mr of 84K. The MAbs defined one antigenic site which could be divided into five epitopes. A correlation between haemagglutination inhibition (HI) and neutralization activity could be seen although one MAb, which recognized a distinct epitope, showed neutralization and no HI activity to PIV2. The reactivity of the MAbs was tested against Sendai virus, parainfluenza virus type 3, simian virus 5 (SV5), mumps virus, Newcastle disease virus, measles virus and canine distemper virus. Only one MAb showed any cross-reaction with a low HI titre to SV5.
