Grey Meril Covid-19 One-step Rt-pcr Kit

We are Antigen test kit Manufacturer. An antigen is a molecule capable of stimulating an immune response. They may be proteins, polysaccharides, lipids or nucleic acids. Each antigen has distinct surface features that are recognized by the immune system. SARS-CoV-2, the virus that causes COVID-19, has several known antigens, including its nucleocapsid phosphoprotein and spike glycoprotein, which are the visible protrusions on its surface.
An antibody is a Y-shaped protein produced by B cells of the immune system in response to exposure to antigens. The tip of each Y-shaped arm contains antigen binding sites (paratopes) that bind to a specific portion of the antigena s surface (epitope).
This binding helps to eliminate antigens from the body, either by direct neutralization or by a tagginga them for elimination by other arms of the immune system. When infected with SARS-CoV-2, the body produces antibodies that bind specifically to the spike proteins and other antigens to help eliminate the virus. This binding can be harnessed to develop antibody and antigen-based diagnostic tests.
