Meaning
An antigen is a protein usually found on the cell membrane of a cell or the surface of a virus.
About Antigens
- Antigens act as locations where certain chemicals can interact with a cell.
- Some antigens are receptor sites where hormones bind in order to change the behaviour of a cell.
- Some antigens are locations where a chemical will bind in order to be taken into the cell.
