Abstract
The present invention provides monoclonal antibodies demonstrating specific reactivity with HIV-1 p24. One monoclonal antibody designated 31-42-19 recognizes an unique epitope on HIV-1 p24 that is not immunogenic in humans. 31-42-19 also reacts with an antigenically cross reactive epitope on HIV-2 p24. Another monoclonal antibody designated 31-90-25 recognizes an epitope within a highly immunogenic region of HIV-1 p24. The present invention also provides cell lines capable of producing these monoclonal antibodies. The invention also includes a highly sensitive enzyme immunoassay for the detection of HIV-1 p24 in biological fluids, using a monoclonal antibody mixture. The present invention further provides methods for the use of these monoclonal antibodies for the detection of anti-HIV-1 p24 antibodies and HIV-2 p24 antigen in biological samples.
