ep·i·tope

 (ĕp′ĭ-tōp′)
n.
A small molecular region of an antigen that binds to a particular antibody or antigen receptor on a T cell; an antigenic determinant. A single antigen can have multiple epitopes.

[epi- + Greek topos, place, spot.]

epitope

(ˈɛpɪˌtəʊp)
n
(Medicine) the site on an antigen at which a specific antibody becomes attached

ep•i•tope

(ˈɛp ɪˌtoʊp)

n.
a site on an antigen at which an antibody can bind, the molecular arrangement of the site determining the specific combining antibody. Also called antigenic determinant .

Several implications of the epitope analysis we have performed argue against hcTnI being globular, at least in the uncomplexed form that was used for immunization: (a) all 16 anti-hcTnI mAbs recognized a continuous epitope markedly; this contrasts with the observation that most mAbs to globular proteins show a conformation-dependent recognition [12] and, therefore, do not react with short peptides; (b) several helices of hcTnI are antigenic, which means that they are probably exposed to the solvent and not packed together as in globular proteins; and (c) we observed that regions connecting the predicted helices of hcTnI are not antigenic; this is in sharp contrast with the fact that turn regions in globular proteins are generally antigenic.
