title: Differentiating pestes des petits ruminants and rinderpest viruses by a novel monoclonal antibody.
abstract: Peste des petits ruminant (PPR) is an acute, febrile, viral disease of small ruminants with great economic importance. PPR and rinderpest (RP) viruses are antigenically related and need to be differentiated serologically. The use of monoclonal antibodies (MAbs) in ELISA for specific diagnostics and separation of PPR and RPV is important. For this purpose, six Balb/c mice were immunized with inactivated antigen from the Nijeria strain. Fusion cloning was performed 3 months later by directly using cloning plates, selecting the hybridoma colonies at an early stage with an inverted microscope, and transferring the colonies into 96-well plates with a micropipette. From 300 wells, nearly 56 hybridoma clones were found, from which, after testing in ELISA, 11 with higher titer were selected. Among these, only two clones were placed for limiting dilution (1H1, 6A12). Only one clone (6A12L1F12) had no cross-reactivity with RP, reacted with the N protein, and was of IgG2 isotype.
