Avian Influenza Virus Ag Rapid Test

AIV Ag Rapid Test Kit use chromatographic immunoassay for the qualitative detection of AIV protein which is the common antigen of all the subgroup of ALV. Sample to be tested is loaded to the sample pad, and then capillary flow along on the test strip. The detection antibody is coupled with colloidal gold as conjugate will mix with the sample fluid. Where AIV antigen is present, a complex is formed by AIV antigen and colloidal gold labelled antibody. The labelled antigen–antibody complex is then bound by a second ‘capture-antibody’ that recognizes the complex, and which is immobilized as T line on the test strip. A positive result therefore generates a visible wine-red line of antigen–antibody complex. A wine-red C line will appear to confirm the test is operated correctly.
