cross-reaction

 [kros´re-ak-shun]
an interaction between an antibody and an antigen closely related to the antigen that specifically stimulated synthesis of the antibody.

cross-re·ac·tion

antibodies evoked by antigens with shared or similar idiotypic determinants may bind or cross-react with each other's respective antigens, even if their antigen-specificity is not identical.

cross-reaction

(krôs′rē-ăk′shən, krŏs′-)
n.
The reaction between an antigen and an antibody that was generated against a different but similar antigen.

cross′-re·act′ v.
cross′-re·ac′tive adj.
cross′-re·ac·tiv′i·ty n.

cross-reaction

Immunology A partial reaction or 'recognition' of an epitope by an antibody generated in response to another antigen

cross-re·ac·tion

(kraws'rē-ak'shŭn)
A specific reaction between an antiserum and an antigen complex other than the antigen complex that evoked the various specific antibodies of the antiserum. It is due to at least one antigenic determinant that is included among the determinants of the other complex.

cross-reaction

The association of an ANTIBODY with an ANTIGEN that differs from the antigen that first stimulated the production of the antibody. Cross reaction is unlikely unless there is close chemical similarity between the two antigens. Some diseases are believed to result because of antigenic similarities between certain body tissues and parts of infecting organisms, such as STREPTOCOCCI.

Cross-reaction

A reaction that occurs in blood testing when a disease agent reacts to the specific antibody for another disease agent. Cross-reactions are common in blood tests for fluke infections because the different species are closely related.

cross-reaction

a reaction which occurs when surface antigenic determinants on different molecules of quite different sources are identical, so that antibody directed against one antigen also reacts with another.
