Covid-19 contains spinous process (s) protein, membrane (m) protein and Nucleocapsid (n) protein. In order to obtain effective treatment, covid-19 rapid diagnosis is very important. Rapid identification can reduce the length of hospital stay, reduce the use of antiviral drugs and reduce the cost of hospitalization, which greatly saves resources. Covid-19 IgM & IgG detection kit (immunochromatography) provides a simple and rapid detection of IgM & IgG antibodies in human blood. Because of its simplicity and rapidity, it is conducive to early treatment and improve efficiency.
[inspection principle]
Covid-19 IgM & IgG detection reagent (hereinafter referred to as covid-19 detection card) adopts the principle of antigen antibody specific binding and immunochromatographic technology, The reagent contains anti human IgM monoclonal antibody (m) and anti human IgG monoclonal antibody (g) pre fixed on the test area (c) on the test strip, Goat anti chicken IgY in the quality control area, anti covid-19 IgM specific protein coupled colloidal gold (m.nc-gc gold standard conjugate) pre fixed on the conjugate release pad and chicken IgY coupled colloidal gold. During the test, drop the sample into the reagent loading hole (s). The sample moves to the detection line by capillary chromatography. If there is IgM antibody against covid-19 in the sample, it will combine with m.nc-gc gold standard conjugate to form igm-m.nc-gc complex. This complex continues to migrate forward under the action of chromatography and is captured by anti human IgM monoclonal antibody previously fixed to the M line to form a wine red band, indicating IgM positive of covid-19; If there is IgG antibody against covid-19 in the sample to be tested, under the action of capillary chromatography, it also binds to m.nc-gc and is captured by g line to form a wine red band, indicating that covid-19 IgG is positive; If M and / or G do not develop color, it indicates that the sample is covid-19 negative; Covid-19 IgM & IgG detection reagent contains a built-in quality control line. Whether IgM & IgG exists in the sample or not, a wine red band will appear in the quality control area (c). The wine red band in the quality control area (c) is the standard to judge whether there are enough samples and whether the chromatography process is smooth.
