title: [The detection and quantitative determination of antigens to the human immunodeficiency virus types 1 and 2].
abstract: Three modifications of ELISA test system for HIV antigen detection are described. They are based on IgG from HIV-1 and HIV-2-infected human sera and monoclonal antibodies against HIV-1 p24 used as immunosorbents. The peroxidase/anti-HIV-IgG conjugate was used in all the test systems. A possibility of quantitative detection of viral antigen in native culture fluids, lysates, and purified virus preparations was demonstrated. The test system for HIV-1 antigen detection cannot be used for HIV-2 antigen detection and vice versa. The diagnostic value of HIV-1 p24 antigen detection consists in the possibility of earlier AIDS identification and monitoring of the disease at various stages. The sensitivity of "p24" assay is 0.5 ng/ml.
