TP Test (Treponema Pallidum Antibody Detection Kit)
Treponema pallidum antibody detection kit coats recombinant treponema pallidum antigen on the detection line and coats anti-mouse lgG polyclonal antibody on the quality control line using double antigen sandwich method of immunochromatography. Colloidal gold conjugates is colloidal gold-labeled recombinant treponema pallidum antigen. In detection, if the sample to be tested contains syphilis antibodies, the sample reacts with gold-labeled conjugates into complex Ab-Ag-Au. Under the effect of chromatography, the reactive complex moves forward to the detecting area along the nitrocellulose membrane and forms Ag-Ab-Ag-Au which will be enriched on the coating line when is captured by solid-phase matter. If syphilis antibody levels ≥ the minimum detectable quantity, it will form a red reaction line in the detecting area. If the sample does not contain syphilis antibody, the red line will not appear in the detecting area and the results are negative this moment.
Specimen: serum, plasma, whole blood. Sensitivity: 2 NCU/ml.
