Understanding Cross-Reactivity

For Lab Professionals. Thyroid Diseases. A drug family can share a common shape to which an antibody will bind. Shellfish Allergy. A patient sensitized to cross-reactive components may still suffer from symptoms; albeit, normally mild-to-moderate symptoms; but by determining the primary sensitization, the patient can be effectively treated.

Depending on the experiment set up there are cross-adsorbed and highly cross-adsorbed secondary antibody varieties. Wagner, S, and H Breiteneder.

Understanding cross-reactions between species can help you to understand multiple sensitizations, for example, those seen in Pollen-Food Allergy Syndrome PFAS. Symptoms that have manifested as a result of cross-reacting antibodies cannot always be distinguished from those caused by genuine sensitization.

Connective Tissue Diseases. Some drug families share a common shape and so an antibody raised to recognise a drug within that group will detect or cross react with all of the drugs within the family. Thyroid Disease. World Allergy Organ J. Secondary antibody selection.

Of note, there is cross-reactivity between chitins a component of exoskeleton of shellfish and insects in dust mites and crustacean shellfish, in the form of a cross-reactive risk protein called tropomyosin.

Drug Classifications. Cross-reactive proteins are more widely distributed and may be shared between a very wide range of allergen sources.

Once the antibody is bound to the drug a colour change occurs, the greater the intensity of this colour change the larger the volume of the drug. Contact Us Now.
