Characterization of antigenic structures on arabis mosaic virus with monoclonal antibodies. 1986

R G Dietzgen

Seven different epitopes on arabis mosaic virus (ArMV) were discerned. Neo-, crypto-, and epitopes exposed on the virion and isolated coat protein were differentiated by their reactivity with monoclonal antibodies in an indirect enzyme-linked immunosorbent assay. The monoclonal antibodies, produced in vitro and in vivo, were of IgGl, IgM and IgA isotype. No epitope exclusively specific for one isolate was found. One epitope was specific for ArMV isolates only. With the common epitopes an operational antigenic map was devised. An immunological relationship between nepoviruses of different serological subgroups was demonstrated. Grapevine fanleaf virus, a member of the ArMV subgroup could not be shown to expose crossreactive epitopes. For serotyping ArMV isolates were discriminated by comparing the reactivity of two or more monoclonal antibodies specific for different epitopes.

UI	MeSH Term	Description	Entries
D009029	Mosaic Viruses	Viruses which produce a mottled appearance of the leaves of plants.	Mosaic Virus,Virus, Mosaic,Viruses, Mosaic
D010944	Plants	Multicellular, eukaryotic life forms of kingdom Plantae. Plants acquired chloroplasts by direct endosymbiosis of CYANOBACTERIA. They are characterized by a mainly photosynthetic mode of nutrition; essentially unlimited growth at localized regions of cell divisions (MERISTEMS); cellulose within cells providing rigidity; the absence of organs of locomotion; absence of nervous and sensory systems; and an alternation of haploid and diploid generations. It is a non-taxonomical term most often referring to LAND PLANTS. In broad sense it includes RHODOPHYTA and GLAUCOPHYTA along with VIRIDIPLANTAE.	Plant
D003429	Cross Reactions	Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen.	Cross Reaction,Reaction, Cross,Reactions, Cross
D006825	Hybridomas	Cells artificially created by fusion of activated lymphocytes with neoplastic cells. The resulting hybrid cells are cloned and produce pure MONOCLONAL ANTIBODIES or T-cell products, identical to those produced by the immunologically competent parent cell.	Hybridoma
D000911	Antibodies, Monoclonal	Antibodies produced by a single clone of cells.	Monoclonal Antibodies,Monoclonal Antibody,Antibody, Monoclonal
D000918	Antibody Specificity	The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.	Antibody Specificities,Specificities, Antibody,Specificity, Antibody
D000956	Antigens, Viral	Substances elaborated by viruses that have antigenic activity.	Viral Antigen,Viral Antigens,Antigen, Viral
