Tags and Cell Markers
Tags, also called antigen epitopes and antigen determinants, refer to the specific region or group of antigen molecules that determine the specificity of an antigen and the structure or sequence that specifically binds with an antibody. The fusion protein containing the target gene and epitope tag was constructed using DNA recombination techniques, and then the fusion protein was identified and purified using a specific tag antibody. Tag antibodies can specifically bind with the corresponding tag fusion protein, making them common tools for research in gene protein expression, signal transduction, and gene function.
Cell markers, also known as cell surface antigens, can be used for the identification and classification of cells. The majority of cell markers are molecules or antigens on the surface of cell membranes. Unique to different cell types, specific markers or antigens not only act as markers for specific cells but also play key functional roles. It is possible to diagnose diseases or direct treatment by identifying the presence of these specific markers.
