[Assay for simultaneous detection of HIV p24 antigen and anti-HIV antibody]. | LitMetric
Objective : To develop a rapid assay for simultaneous detection of HIV p24 antigen (Ag) and anti-HIV antibody (Ab).Methods : HIV-1 gp41 antigen and HIV-2 gp36 antigen were expressed by recombinant baculovirus insect system and purified by immunochromatography. p24 monoclonal antibody (mAb) was obtained from p24 hybridoma cell line. Purified antigen and mAb were dot blotted to nitrocellular membrane; 20 nm colloidal gold-anti-human IgG ab and p24 ab complex were used for this test. Previously detected 39 sera specimens were tested in this study to compare with the result of HIV test with commercial HIV test kit.Results : 20 mg/L purified gp41 Ag and gp36 Ag were obtained from recombinant baculovirus-insect cell system; 1.5 mg/L p24 mAb was obtained from p24 mAb hybridoma cell line. Compared the test result of 39 sera with commercial HIV test kits, consistency rate was 100%.Conclusions : The rapid assay for simultaneous detection of HIV p24 antigen and anti-HIV antibody provides a simple, sensitive and reliable test for HIV diagnosis.
