Product Information

The methods currently used to diagnose COVID-19 include nucleic acid detection and IgG/IgE antibody detection. The establishment of rapid and accurate specific detection methods is of great significance to the control of the epidemic. Antigen and antibody detection reagents may achieve high-throughput screening of the virus. . Antigen testing can detect various types of samples to find protein molecules on the surface of the virus. This method can get results faster, and it can also conduct preliminary rapid screening of COVID-19 in various samples.

Principles

This kit adopts the principle of double antibody sandwich method by colloidal gold immunochromatography to qualitatively detect the COVID-19 novel coronavirus antigen in human throat swabs/nasopharyngeal swabs. The NC membrane is coated with a testing line (T line) and a quality control line (C line). The T wire is coated with antibodies against the new coronavirus (COVID-19). The C wire is coated with goat anti-mouse antibodies. When the concentration of the corresponding analyte in the specimen is not less than the minimum detection limit, it will react with the colloidal gold-labeled antibody to form a complex. Under the action of chromatography, the reaction complex moves forward along the nitrocellulose membrane to the detection area (T ), which reacts with the pre-coated antibody on the nitrocellulose membrane to form an antibody-antigen-antibody complex, and finally forms a red reaction line in the detection area, and the result is positive at this time. When the sample does not contain the corresponding analyte or the concentration of the analyte is lower than the minimum detection limit, no red reaction line appears in the detection area, and it is negative at this time. Regardless of whether the specimen contains the corresponding test substance, the quality control area (C) will form a red reaction line.
