DEFINITION

Classification: 435/327

Immunoglobulin or antibody is anti-idiotypic:

(under subclass 326) Subject matter involving an animal cell which produces an antibody or antibody fragment that binds another antibody at one of its idiotopes.

(1) Note. An idiotope is an antigenic determinant in the variable region of the antibody.

(2) Note. An idiotype is that set of idiotopes characteristic of a particular antibody.

(3) Note. Included in this subclass are "internal image" antibodies which are a subset of anti-idiotypic antibodies that mimic the antigen in their ability to elicit antibodies that bind said antigen.

(4) Note. It is suggested that the patents in this subclass be cross-referenced to Class 530, in the appropriate subclasses, 387.1 through 389.8, that provide for the binding specificity of the antibodies bound by the anti-idiotypic antibodies, if disclosed.
