Enterovirus 71 (EV71)-IgM Detection Kit (Colloidal Gold Method) is a lateral flow immunoassay for the qualitative detection of IgM-class antibodies to human Enterovirus 71 (EV71) in serum, plasma or whole blood samples. It is intended to be used as a screening test and provides a preliminary test result for early diagnosis and management of patients related to infection with EV71.
【TEST PRINCIPLE】
This kit adopts colloidal gold-immunochromatography assay (GICA).
The test card contains:
1. Colloidal gold-labeled antigen and quality control antibody complex.
2. Nitrocellulose membranes immobilized with one test line (T line) and one quality control line (C line).
When an appropriate amount of sample is added to the sample well of the test card, the sample will move forward along the test card under capillary action.
If the sample contains an IgM antibody of EV71, the antibody will bind to the colloidal gold-labeled EV71 antigen, and the immune complex will be captured by the monoclonal anti-human IgM antibody immobilized on the nitrocellulose membrane to form a purple/red T line , showing that the sample is positive for IgM antibody.
