Specific amino acid sequence of a foreign antigen, such as a virus, that an antibody recognizes, binds to, and reacts against.
A site on an antigen recognized by antibody; epitopes are also called antigenic determinants. A T-cell epitope is a short peptide derived from a protein antigen. It binds to an MHC molecule and is recognized by a particular cell.
an amino acid (or other) sequence that effects formation of an antibody
The antibody-binding region of an antigenic molecule.
Site on an antigen and an antibody allowing the antibody to recognize and bind specifically to this antigen.
the part of an antigen recognized by the immune system
a carbohydrate molecule that determines whether or not specific antibodies will initiate an attack
a functional recognition site that binds by a specific monoclonal antibody
a portion of a molecule to which an antibody binds
a region of a polypeptide capable of binding an immunoglobulin generated in response to contact with an antigen
a small piece of the antigen to which the antibody binds
A chemical structure capable of eliciting an immune cell response and of being specifically recognized by molecules of immune recognition (e.g., immunoglobulins, T-cell receptors, etc.).
The part of an antigen molecule that binds to an antibody; also called antigenic determinant.
A unique molecular shape or sequence carried on a microorganism that triggers a specific antibody or cellular immune response.
see antigenic determinant
the site on an antigenic molecule to which a T-cell receptor responds or an antibody binds to. Protein antigens can contain more than one epitope (also known as an antigenic determinant).
a specific part on the surface of a virus that is targeted for destruction by the body's immune system.
The region, or part, of the surface of a foreign substance that is recognised by an antibody.
a unique shape or a marker on the surface of an antigen that triggers an antibody response.
a specific area on the surface of an antigen (see above) that can cause an immune response and can bind with a specific antibody produced by the immune system.
Specific region on an antigen which is recognized by a specific antibody or T-cell.
antigen determinant (something to which an antibody will attach).
part of the antigen which is specifically recognized by an antibody (B cell epitope) or by a T cell receptor (T cell epitope).
a characteristic shape or marker on an antigens surface.
The structure on the antigen that is recognized by an antigen receptor (antibody or T-cell receptor).
A unique shape or marker carried on an antigen's surface that triggers a corresponding antibody response. See Antibodies; Antigen.
A specific site on an immunogen that stimulates specific immune responses, such as the production of antibodies or activation of immune cells.
A single antigenic determinant on a protein that is recognized by an antibody. A single protein can have many epitopes.
or antigenic determinant. The small portion of an antigen that combines with a specific antibody. A single antigen molecule may carry several different epitopes.
also known as antigenic determinant. A localized region on the surface of an antigen which antibody molecules can identify and bind.
Any part of a molecule that acts as an antigenic determinant: a macromolecule can contain many different epitopes each capable of stimulating production of a different specific antibody. Nagel et al. (eds), 1991
An alternative term for antigenic determinant.
small antigenic part of a molecule.
is an antigenic determinant.
The smallest part of an antigen that can be recognised by an antibody.
An epitope is the part of a macromolecule that is recognized by the immune system, specifically by antibodies, B cells, or cytotoxic T cells. Although epitopes are usually thought to be derived from nonself proteins, sequences derived from the host that can be recognized are also classified as epitopes.
