Antigens are large molecules, usually proteins, on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, and foreign particles.Any substance capable of triggering an immune response is called an antigen.kip to content. Antibodies, also called immunoglobulins, are large Y-shaped proteins which function to identify and help remove foreign antigens or targets such as viruses and bacteria.
In summary an antigen is a molecule that binds to Ag-specific receptors, but cannot induce an immune response in the body by itself.The term originally described a structural molecule that binds specifically to an antibody.It expanded to refer to any molecule or a linear molecular fragment that can be recognized by highly variable antigen receptors (B-cell receptor or T-cell receptor) of the adaptive immune system.he term originally described a structural molecule that binds specifically to an antibody.
