Monoclonal antibody specific for an epitope of inactivated feline immunodeficiency-encoded glycoprotein
View Patent ↗The present invention provides a monoclonal antibody specific for an epitope which is unique to the surface protein component of an inactivated feline immunodeficiency virus (FIV) envelope glycoprotein. Said antibody is useful for the quantification of inactivated FIV or the determination of the potency of an inactivated FIV vaccine.
1. Monoclonal antibody produced from the cell line deposited at the American Type Culture Collection (ATCC) under Accession No. PTA-4837.
2. A method for the detection of an epitope of an inactivated FIV-encoded glycoprotein in a sample comprising: contacting said sample with a monoclonal antibody produced from the cell line deposited at the American Type Culture Collection (ATCC) under Accession No. PTA-4837 or a clone thereof, wherein the monoclonal antibody specifically reacts with or recognizes the epitope of the inactivated FIV or inactivated FIV glycoprotein but does not react with or recognize live FIV or live FIV glycoprotein, to form a complex; and detecting said complex.
3. A hybridoma cell line deposited at the American Type Culture Collection under Accession No. PTA-4837, suitable for obtaining monoclonal antibodies specific for an epitope of an inactivated FIV-encoded glycoprotein, prepared by immunizing a suitable host with a partially purified, inactivated FIV, screening the host for high FIV-specific antibody response, fusing splenocytes from said host with a suitable myeloma cell line, and screening hybridomas for specific reactivity with inactivated FIV wherein there is no reaction with or recognition of live FIV.
4. The cell line deposited at the American Type Culture Collection under Accession No. PTA-4837.
