- of or relating to antigens
- (antigen) any substance (as a toxin or enzyme) that stimulates an immune response in the body (especially the production of antibodies)
- An antigen is a molecule recognized by the immune system. Originally the term came from antibody generator and was a molecule that binds specifically to an antibody, but the term now also refers to any molecule or molecular fragment that can be bound by a major histocompatibility complex (MHC) ...
- Antigenicity is the ability of a chemical structure (referred to as an Antigen) to bind specifically with certain products of adaptive immunity: T cell receptors or Antibodies (a.k.a. B cell receptors). ...
- (A antigen) The ABO blood group system is the most important blood type system (or blood group system) in human blood transfusion. ...
- (antigen) A substance that induces an immune response, usually foreign
- (Antigen) a substance that reacts with antibodies or memory T cells to give rise to an immune reaction. An antigen that binds with a specific antibody or T cell can give rise to allergy.
- (Antigen) A substance, usually a protein, that the body perceives as foreign.
- (antigen) A protein or other molecule that can elicit an immune response; the antibody protein that is produced binds to the antigen.
- (antigen (Ag)) A molecule which induces the formation of antibody.
- (Antigen) A protein on the surface of a virus, bacteria or cell that can stimulate the immune system to produce antibodies as a defense mechanism.
- (Antigen) Proteins located on the surface of all cells. The immune System uses antigens to determine whether cells are a necessary part of the body or need to be destroyed.
- (antigen) a protein marker on the surface of cells that identifies the cell.
- An antigen is any substance that the body identifies as potentially dangerous and against which it produces a defence (an antibody).
- (Antigen) Any foreign material that is specifically bound by specific antibody or specific lymphocytes; also used loosely to describe materials used for immunization. Antigens may also be immunogens if they are able to trigger an immune response, or haptens if not.
- (Antigen) a structure foreign to the body, such as a virus. The body usually responds to antigens by producing antibodies.
- (Antigen) Any substance capable of stimulating a specific immune response (i.e., a specific antibody) in the body.
- (antigen) a marker protein on cells of the body or foreign substances, such as a virus or bacteria
- (antigen) Usually a protein or carbohydrate substance capable of stimulating an immune response
- (antigen) Anything that stimulates the production of a specific antibody by the immune system.
- (antigen) any substance that stimulates the immune system to produce antibodies. Antigens are often foreign substances such as invading bacteria or viruses.
- (Antigen) A protein "recognized" by the body as being foreign; it results in the production of specific antibodies directed against it.
- (antigen) Virus coded cell surface antigens that appear soon after the infection of a cell by virus, but before virus replication has begun. A foreign substance or organism which causes the body to form an antibody that responds only to that antigen. ...
- (Antigen) A foreign or nonnative substance from the environment recognized by the body as a threat. Antigens are usually capable of inducing formation of antibodies.
- An antigen is any substance (bacterium, virus, or single molecule), usually a protein, but sometimes a sugar or fat that stimulates an immune reaction in the body. This immune reaction may result in the production of antibody or a cellular immune reaction.
