Monoclonal antibodies to feline sarcoma virus gag and fes gene translational products. 1983

F Veronese, and G J Kelloff, and F H Reynolds, and R W Hill, and J R Stephenson

A series of hybridomas have been isolated which produce monoclonal antibodies directed against polyprotein gene products of the Gardner, Snyder-Theilen, and McDonough strains of FeSV. Within these are representatives of several immunoglobulin classes including IgG1, IgG2a, IgG2b, and IgM. Antibody produced by one hybridoma recognizes immunologic determinants localized within an FeLV gag gene structural component (p15) common to polyproteins encoded by all three FeSV isolates whereas antibody produced by a second is specific for p30 determinants unique to P170gag-fms. Additional hybridomas secrete antibody directed against v-fes-encoded determinants common to the Gardner and Snyder-Theilen FeSV-encoded polyproteins. GA P110gag-fes and ST P85gag-fes immuno-precipitated by antibody directed against p15 exhibit tyrosine-specific protein kinase activity but lack such activity when precipitated by antibody specific for their acquired sequence (v-fes) components.

UI MeSH Term Description Entries
D005253 Sarcoma Viruses, Feline Species of GAMMARETROVIRUS isolated from fibrosarcoma in cats. The viruses are actually recombinant feline leukemia viruses (FeLV) where part of the genome has been replaced by cellular oncogenes. It is unique to individuals and not transmitted naturally to other cats. FeSVs are replication defective and require FeLV to reproduce.

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
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D000914 Antibodies, Viral Immunoglobulins produced in response to VIRAL ANTIGENS. Viral Antibodies
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
D012190 Retroviridae Family of RNA viruses that infects birds and mammals and encodes the enzyme reverse transcriptase. The family contains seven genera: DELTARETROVIRUS; LENTIVIRUS; RETROVIRUSES TYPE B, MAMMALIAN; ALPHARETROVIRUS; GAMMARETROVIRUS; RETROVIRUSES TYPE D; and SPUMAVIRUS. A key feature of retrovirus biology is the synthesis of a DNA copy of the genome which is integrated into cellular DNA. After integration it is sometimes not expressed but maintained in a latent state (PROVIRUSES).
