Epitope - Wikipedia
An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells. The part of an antibody that binds to the epitope is called a paratope.

2021年5月10日 · An epitope is the part of an antigen that the host’s immune system recognizes, eliciting the immune response to an invading pathogen.
Epitope | Description & Function | Britannica
Epitope, portion of a foreign protein, or antigen, that is capable of stimulating an immune response. An epitope is the part of the antigen that binds to a specific antigen receptor on the surface of a B cell. Binding between the receptor and epitope occurs only if their structures are.
Epitopes: Types, Function, Epitope Spreading - Microbe Online
2021年6月1日 · Epitopes, also known as antigenic determinants, are the immunologically active discrete sites on the antigen molecule that physically bind to antibodies, B-cell receptors, or T-cell receptors. When an antibody binds to an antigen, it isn’t binding to the entire antigen but to a segment of that antigen known as an epitope.
Epitope - an overview | ScienceDirect Topics
An epitope is a specific location on the surface of an antigen that has a particular molecular structure and that is recognized by a particular antibody or a set of specific antibodies that the epitope elicits during the immune response.

2023年8月31日 · The actual portions or fragments of an antigen that react with receptors on B-lymphocytes and T-lymphocytes, as well as with free antibody molecules, are called epitopes or antigenic determinants. The size of an epitope is generally thought to be equivalent to 5-15 amino acids or 3-4 sugar residues.
Epitope - an overview | ScienceDirect Topics
An epitope or antigenic determinant is a group of amino acids or other chemical groups exposed on the surface of a molecule, frequently a protein, which can generate an antigenic response and bind antibody. From: Immunoassay, 1996

2024年5月21日 · An epitope is the part of a protein which is recognized by the immune system. They are recognized by specific T cells, B cells, and the antibody produced by B cells. When these cells recognize and are activated by specific epitopes, they begin mounting an …
Epitope | definition of epitope by Medical dictionary
epitope Any site on a biomolecule (antigenic determinant) which can evoke antibody formation. The minimum size of a molecule capable of evoking antibody formation is about 1 kD; if the molecule is smaller, as with haptens, it may evoke an immune response by …
Epitope Definition & Meaning - Merriam-Webster
The meaning of EPITOPE is a molecular region on the surface of an antigen capable of eliciting an immune response and of combining with the specific antibody produced by such a response —called also determinant, antigenic determinant.
