The case of viral pneumonia was first detected in 2019, and the new coronavirus (COVID-19) that caused the disease was discovered. On January 12, 2020, the new viral pneumonia was named "COVID-19" by the World Health Organization and the corresponding virus was named "SARS-CoV-2". The virus is coated with round or elliptical particles, which are polymorphic with a diameter of 60-140nm. Its genetic characteristics are significantly different from SARSr-CoV and MERSr-CoV and have more than 85% homology with β-SARS- like coronavirus (β-SL-CoVZC45). The virus can be excreted through respiratory secretions and spread through saliva, sneezing, contact and aerosols. It is very necessary to carry out an effective antigen covid test through the covid antigen testing kit.
SARS-CoV-2 Antigen Test Kit (Saliva) (Colloidal Gold) use the double-antibody sandwich method to qualitatively detect SARS-CoV-2 in saliva.
SARS-CoV-2 Antigen Test Kit (Saliva) (Colloidal Gold) is the kit based on nitrocellulose membrane and qualitative immunoassay to detect SARS- CoV-2 in saliva.
During the test, add the saliva sample to the buffer and mix well.
After adding it to the sample well, it will react with the bound SARS-CoV-2-N22 antibody-coated gold nanoparticles to form an antigen-antibody complex.
This complex migrates forward along the test strip on the chromatographic membrane, interacts and binds with the immobilized SARS-CoV-2-N21 antibody, and immobilizes the antigen in the test line area of the test.
If the specimen contains SARS-CoV-2, a color line will appear in the test line area, indicating that the result is positive.
Otherwise, there will be no color line in the area, indicating a negative result. In order to determine the validity of the test strip, a color line will always appear in the control line area, indicating that an appropriate volume of sample has been added and reacted with the quality control antibody on the membrane.
