Analysis mode


PRINCIPLE The microtitration plate wells are coated with HIV-1 and HIV-2 recombinant antigens. The sample is incubated in the wells. If sample contains antibodies against HIV-1 or HIV-2 they will bind to the antigens present in the wells. The unbound fraction is eliminated by washing. In the next step, is added the conjugate which contains the same antigens than the plate conjugated to peroxidase. They will bind to the antibodies if they were present in the sample. The unbound conjugate is removed by washing. Then, a solution containing tetramethylbenzidine (TMB) and hydrogen peroxide is added. The reactive samples develop a light blue color that changes to yellow when the reaction is stopped with sulfuric acid. PROVIDED REAGENTS Coated microtitration plate: microtitration plate with removable strips and 96 wells, coated with HIV-1 and HIV-2 recombinant antigens. Conjugate: recombinant antigens bound to peroxidase. Red color. Substrate: tetramethylbenzidine (TMB) and hydrogen peroxide solution. Stopper: 2 N sulfuric acid. Concentrated Wash Buffer: saline buffer with surfactant agent (25x). Green color. Positive Control: inactivated human serum containing antiHIV-1 and anti-HIV-2 antibodies. Orange color.
