WebTissue cross-reactivity (TCR) studies are key in the development of monoclonal antibodies and other related biologics to ensure that the experimental antibody or biologic does … WebJan 17, 2024 · A Tissue cross-reactivity (TCR) study is a method used to identify non-specific and specific binding of test biologics in different types of human or animal tissues. This information is vital in ensuring that experimental antibodies do not bind to epitopes other than the targeted sites, thus minimizing the risk of treatment-related toxicity.

WebFeb 9, 2007 · The prediction of allergen cross-reactivity is currently largely based on linear sequence data, but will soon include 3D information on homology among surface exposed residues. ... In biological systems (e.g. skin test, cellular in vitro assays), assessment of cross-reactivity largely depends on direct testing, and thus on statistical ... Cross-reactivity, in a general sense, is the reactivity of an observed agent which initiates reactions outside the main reaction expected. This has implications for any kind of test or assay, including diagnostic tests in medicine, and can be a cause of false positives. In immunology, the definition of cross-reactivity refers specifically to the reaction of the immune system to antigens. There can be cross-reactivity between the immune system and the antigens of two different pathogens, or bet…
