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.
An Introduction to Antibodies: Antigens, Epitopes and
The small site on an antigen to which a complementary antibody may specifically bind is called an epitope or antigenic determinant. This is usually one to six monosaccharides or five to eight amino acid residues on the surface of the antigen.
Epitope mapping - Wikipedia
In immunology, epitope mapping is the process of experimentally identifying the binding site, or epitope, of an antibody on its target antigen (usually, on a protein). [1][2][3] Identification and characterization of antibody binding sites aid in the discovery and development of new therapeutics, vaccines, and diagnostics. [4][5][6][7][8] Epitop...
12.2: Antigens and Epitopes - Biology LibreTexts
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.

2021年6月1日 · 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. The part of an immunoglobulin that binds and fits the epitope is called a paratope .
What is an Epitope - Pacific Immunology
An epitope refers to the specific target against which an individual antibody binds. When an antibody binds to a protein, it isn’t binding to the entire full-length protein. Instead, it is binding to a to a segment of that protein known as an epitope.
Epitope binning is a term used to describe segmentation of a panel of monoclonal antibodies (mAbs) into “bins” based upon the antigen region, or epitope, bound by each antibody. This grouping is performed using cross competition assays, in which the competitive binding of antibody pairs to a specific antigen is characterized.

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.
An Introduction to Epitope Mapping - PubMed
Information about the binding epitope of an antibody can provide important mechanistic insights and indicate for what applications an antibody might be useful. Therefore, a variety of epitope mapping techniques have been developed to localize such regions.
Characterizing Epitope Binding Regions of Entire Antibody Panels …
These two analyses together provide elegant, biologically-centered visualizations characterizing potential binding patterns for an entire Ab panel. Taking the epitope binding regions as hypothesized regions that are generally antigenic allows the design of …
Epitope - an overview | ScienceDirect Topics
An epitope, also called an antigenic determinant, is a portion of an antigen that is recognized specifically by antibodies, B and/or T cells of the host immune system which is able to stimulate an immune response. The binding of an epitope to surface antigen receptors occurs by specific interaction only when their structures are complementary.

2021年1月1日 · The epitope is one of the most critical parameters for antibody–antigen binding. Knowing the epitope when using an antibody as a diagnostic reagent makes the experimental conclusions clear and relevant.
Epitope binning is a critical step in which a library of mAbs specific to a given antigen are grouped into “bins” based on the epitopes they bind to.
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

Antibodies 101: Epitope Availability - Addgene
2022年1月11日 · The answer is simple: epitope availability. An antibody can only bind to a target, or epitope, that it can access. If the epitope is hidden, perhaps in the pocket of a folded protein, or blocked by something bound to the protein, the antibody can't bind to it.
Epitope Mapping - an overview | ScienceDirect Topics
Epitope mapping, or determination of the antigen-binding site to an antibody, is a useful tool in identifying B cell epitopes of a protein. This procedure necessitates having a panel of monoclonal or polyclonal antibodies available against the protein.

2024年11月22日 · Although this could be reflective of true interaction patterns, we lean towards a different explanation: non-participation of most CDR3 AAs in epitope binding. Since for most CDR3-epitope pairs, it is not known which AAs in a CDR3 form a bond with which AAs in a cognate epitope, these interaction patterns were not considered when the matrix was ...
