WebDec 23, 2003 · P24 antigen assay was widely used for evaluating HIV-1 NAb by detecting the reduction of p24 antigen production caused by NAbs [ 9 ]. To detect the reliability of the improved microtiter neutralization assay, both assays were performed with the same host cells, cell densities and virus inoculum. Webp24 test uses monoclonal antibodies. When p24 antigen is present it sticks to the antibody and the enzyme linked antibody causes a color change. The test is generally positive from about 1–3 wk following infection. Once the pt starts to produce their own antibodies, the p24 will usually be negative although they are infected.
