Immunoassay

Immunoassays are bioanalytical strategies that utilize antigen-antibody reactions to identify specific molecules with high specificity and sensitivity. Immunoassay test is widely applied in the detection and analysis of various antigens, antibodies, and enzymes which plays a vital role in clinical diagnosis and significantly improves the efficiency of diagnosing and managing the health condition of the patient.

Daan Gene's immunological diagnostic platform has developed the COVID-19 rapid test kit and chemiluminescence immunoassay analyzer to advance the diagnosis process. Our COVID-19 rapid-test kit uses colloidal gold and FIA technology, presenting diagnostic results in 15 minutes with high sensitivity and specificity. Daan Gene's fully automatic immunoassay analyzer machine can test speed up to 120 tests per hour and advances the diagnostic effort.

Immunoassays are based on a biochemical method to detect the unknown analytes by observing specific antigen-antibody reactions. Immunoassays utilize many different labels to allow the discovery of antibodies and antigens. The labels are usually conjugated and chemical-linked to the target antibodies and antigens and could be divided into several types according to various methods, which include: Fluorescent immunoassay (FIA), Chemiluminescence immunoassay (CLIA), Colloidal gold immunochromatography, enzyme-linked immunosorbent assay (ELISA) and etc.
