Easysweet COVID-19 Test Kit is a new coronavirus detection method launched after nucleic acid detection, virus whole gene sequencing and antibody detection. It uses the indicator band on the test card to reflect whether there is specific antigen in the sample. . So what is the principle of antigen detection? It mainly uses the principle of specific combination of antigen and antibody, and the existence of antigen can be detected by antibody, thereby proving that there is a new coronavirus in the sample.
1. What does Easysweet COVID-19 Test Kit mean
Antigen detection is to coat the test card with the specific antibody of the new crown, and then react with the specific antigen in the sample, and use the indicator strip on the test card to reflect whether there is a specific antigen in the sample. a detection method.
The difference between it and the nucleic acid test is that the nucleic acid test detects the genome of the new coronavirus, and this antigen test coats the outer capsid of the gene, and the detection of this outer capsid is the detection of the protein, and the protein is actually the antigen part of the virus.
2. What is the principle of antigen detection?
Knowing what the Easysweet COVID-19 Test Kit is, let's explore the principles of the COVID-19 Test Kit in more depth:
The COVID-19 Test Kit is a protein on the surface of the virus.
The structural proteins of the new coronavirus include S protein, N protein, M protein and E protein. Once the human body is infected with the virus, these structural proteins can act as immunogens to stimulate plasma cells to produce specific antibodies. These proteins contain multiple antigenic epitopes, which can use the principle of specific binding of antigens and antibodies to detect the presence of antigens through antibodies, thereby proving that there is a new coronavirus in the sample.
Easysweet COVID-19 Test Kit can be tested quickly and in a large area. It is suitable for places where fast results are required.If you want to purchase from China, please feel free to CONTACT US.
