HG Rapid Test FIV is a chromatographic immunoassay kit for rapid and qualitative detection ofthe antibodies"against feline immunodeficiency virus (FIV) in feline blood. The nitrocellulose membrane of the kit is immobilized with FlV-specific antigen in testline and with anti-mouse antibodies in the control line.And also,FIV-specific antigen is conjugated to the colloidal gold particles.This conjugate is placed on a polyester or glass fiber as conjugate pad.When the sample is dropped into the sample well on the device, the solubilized conjugate migrates with the sample by passive diffusion and both the conjugate and sample come into contact with the antibody that immobilized onto the nitrocellulose. If the sample contains FIV antibodies, the result is visible as red line within ~10minutes in the test line on the membrane.The solution continues to migrate to encounter a control reagent that binds a control conjugate,thereby producing another red control line.
