Detailed description
Canine parvovirus antigen rapid test kit uses the principle of double antibody sandwich method to qualitatively detect canine parvovirus antigen in dog feces. The gold standard dog parvovirus antibody 1 was used as the indicator marker, and the detection region (T) and the control region (C) on the nitrocellulose membrane were coated with canine parvovirus antibody 2 and sheep anti-chicken, respectively. At the time of detection, the sample is chromatographic under capillary effects. If the tested sample contains canine parvovirus antigen, gold standard antibody 1 forms an antigen-antibody complex with canine parvovirus, and combines with canine parvovirus antibody 2 fixed in the detection area during chromatography to form an “antibody 1-antigen-antibody 2″ sandwich, resulting in a purple-red band in the detection area (T); Conversely, no purple-red bands appear in the detection region (T); Regardless of the presence or absence of canine parvovirus antigen in the sample, the IgY complex of gold standard chicken will continue to be layered upward to the control region (C), and a purplish-red band will appear. The purple-red band presented in the control area (C) is the standard for judging whether the chromatography process is normal, and also serves as the internal control standard for reagents.
