The invention relates to a sensitizing immunochromatographic kit for sensitive detection of novel coronavirus antibodies. The kit introduces a controllable copper growth technology on the basis of colloidal gold immunochromatographic test strips to amplify its detection line colloidal gold probe The optical signal intensity is high, so as to achieve highly sensitive detection of the object to be tested. The kit includes a colloidal gold immunochromatographic test strip and a copper growth solution, and the colloidal gold immunochromatographic test strip is sequentially fixed on a PVC plastic bottom plate by a sample pad, a binding pad, a nitrocellulose membrane and an absorbent paper; The copper growth solution includes copper growth solution A and copper growth solution B. The kit provided by the invention is simple in operation, high in sensitivity, good in stability, fast in detection speed (20-30 min), easy to read in results, and does not require other auxiliary instruments and equipment, and can be used for on-site fast and ultra-sensitive detection of clinical and emergencies and Large-scale epidemiological investigation. |
