cross-reaction Syllabification: cross-re·ac·tion
Pronunciation: /ˌkrôsrēˈakSH(ə)n/

Definition of cross-reaction in English:


The reaction of an antibody with an antigen other than the one that gave rise to it.
Example sentences
  • Cross reactions occur between retroviral glycoproteins and lymphocyte surface receptors.
  • Participants with a history of adverse reactions to peas, beans, or peanuts were excluded because of possible cross reactions to soya protein.
  • Prions exist in very low concentrations in the body, and the cross reaction with other proteins makes the identification of these prions difficult.


Example sentences
  • The putative motor protein, cross-reacting with antimyosin antibodies, was shown to be associated with the surface of isolated Lemna chloroplasts.
  • It was necessary to supplement blood with human fibrinogen because the antibody does not cross-react with canine fibrin.
  • However, studies have shown that native DNA might actually be the cross-reacting antigen whereas modified nucleic acid polymers stimulate antibody response.
Example sentences
  • In contrast, more cross-reactive antibodies are believed to be more flexible and involve less specific contacts.
  • Those results led the authors to believe that either patients were exposed simultaneously to the 3 molds, or that these antibodies were the result of cross-reactive antigens.
  • In contrast, the cross-reactive behavior of HH8 is characterized by fewer of these interactions.
Example sentences
  • In contrast, hydrophobic driven binding and low levels of electrostatic interactions are associated with conformational flexibility and cross-reactivity.
  • Situations of cross-contamination, cross-reactivity, and cross-hybridization all point to the benefit of evaluating an assay for false-positive and false-negative results.
  • Because of the possibility of cross-reactivity, patients with immediate hypersensitivity to penicillin should not be treated with a cephalosporin.
