Twenty-four monoclonal antibodies (MAbs) against rinderpest virus (RPV) were established and characterized by several serological tests. Of the 24 MAbs. 10 recognized the nucleoprotein (NP), six the phosphoprotein (P), four the haemagglutinin (H), and two the fusion (F) protein as determined by radioimmunoprecipitation assay. The specificities of the remaining two MAbs could not be determined. From a competitive binding assay using MAbs against each structural protein, at least five, four and two separate antigenic sites were identified on the NP, P and H proteins, respectively. MAbs against the H protein neutralized the infectivity of the virus, but those against the F protein were only neutralizing in the presence of guinea-pig complement. The reactivities of each of the MAbs for other strains of morbillivirus were tested using an indirect immunofluorescent antibody assay. The MAbs against four out five antigenic sites on the NP showed cross-reactivity amongst all the strains of morbillivirus tested whereas the fifth antibody reacted only with RPV. Of the antibodies specific for the P protein, the antibody against one site was cross-reactive with all the strains of RPV, measles virus (MV) and canine distemper virus (CDV), the antibody against another site was reactive with RPV and MV but not with CDV, and the antibodies against the other two sites were specific for RPV.

D001667 Binding, Competitive The interaction of two or more substrates or ligands with the same binding site. The displacement of one by the other is used in quantitative and selective affinity measurements. Competitive Binding
D012302 Rinderpest virus A species of MORBILLIVIRUS causing cattle plague, a disease with high mortality. Sheep, goats, pigs, and other animals of the order Artiodactyla can also be infected.
D013045 Species Specificity The restriction of a characteristic behavior, anatomical structure or physical system, such as immune response; metabolic response, or gene or gene variant to the members of one species. It refers to that property which differentiates one species from another but it is also used for phylogenetic levels higher or lower than the species. Species Specificities,Specificities, Species,Specificity, Species
D015678 Viral Structural Proteins Viral proteins that are components of the mature assembled VIRUS PARTICLES. They may include nucleocapsid core proteins (gag proteins), enzymes packaged within the virus particle (pol proteins), and membrane components (env proteins). These do not include the proteins encoded in the VIRAL GENOME that are produced in infected cells but which are not packaged in the mature virus particle,i.e. the so called non-structural proteins (VIRAL NONSTRUCTURAL PROTEINS).
