The assay starts with a sample applied to the sample well.
A recombinant HIV antigen conjugated to colloidal gold embedded in the sample pad reacts with the HIV antibody present in whole blood, serum or plasma forming conjugate/HIV antibody complex.
As the mixture is allowed to migrate along the test strip, the conjugate/HIV antibody complex is captured by recombinant HIV antigen immobilized on a membrane forming a coloured test line in the test region.
A negative sample does not produce a test line due to the absence of colloidal gold conjugate/HIV antibody complex. The antigens used in the conjugate test are recombinant proteins that correspond to highly immunoreactive regions of HIV1 and HIV2.
A coloured control line in the control region appears at the end of test procedure regardless of test result. This control line is the result of colloidal gold conjugate binding to the anti-HIV antibody immobilized on the membrane. The control line indicates that the colloidal gold conjugate is functional.
Two test lines are coated on the membrane; on T1 region recombinant gp41, p24, and gp120 are immobilized; most of HIV I or HIV II infected samples give positive results on T1 region; On T2 region a recombinant gp36 is coated, which is HIV II specific, and a positive result appearing on T2 region indicates a HIVⅡ positive samples.
Our Anti-HIV(1&2) Tri-line Test is an immunochromatographic (rapid) test for the qualitative detection of antibodies of all isotypes (IgG,IgM,IgA) specific to HIV-1 including subtype O and HIV-2 simultaneously, in human whole blood, serum or plasma.
