id·i·o·type

(id'ē-ō-tīp),
Collection of idiotopes within the variable region that confers on an immunoglobulin molecule an antigenic specificity and is frequently a unique attribute of a given antibody in a given animal. It is the product of a limited number of B lymphocyte clones; also found on the T-cell receptor. See: idiotope.

idiotype

(ĭd′ē-ə-tīp′)
n.
1. A set of one or more antigenic determinants specific to the variable region of an immunoglobulin molecule.
2. A set of immunoglobin molecules that have the same antigen-binding specificity in their variable regions.

idiotype

[id′ē·ətīp′]
Etymology: Gk, idios + typos, mark
the portion of an immunoglobulin molecule that confers the molecule's unique character, most often including its antigen-binding site.

id·i·o·type

(id'ē-ō-tīp)
A determinant that confers on an immunoglobulin molecule an antigenic "individuality" and is frequently a unique attribute of a given antibody in a given animal.

idiotype

unique part of the variable region of an antibody that can itself act as an antigen for another ANTIBODY. see ANTIIDIOTYPE.

idiotype (iˈ·dē·ō·tīpˑ),

n the region of an immunoglobulin molecule responsible for the unique characteristics of the molecule. In most cases, this includes the antigen-binding location.

idiotype

the antigenic characteristic of the variable region of an antibody. A set of idiotopes. Called also Id.

cross-reacting idiotype (IdX)
one that is present on other immunoglobulins produced in response to the same antigen, permitting a cross reaction. See also cross-reaction.
