TCR Specificity Assay

Based on the outstanding expertise and rich experience, Creative Biolabs has specially developed a system approach of TCR generation and optimization for TCR development. Our technical experts are looking forward to designing a strategy to carry out TCR development for your assays and will be able to recommend a TCR specificity assay method to meet your project needs.

The function of T lymphocytes as orchestrators and effectors of the adaptive immune response is directed by the specificity of their T cell receptors (TCRs). By transferring into T cells the genes encoding antigen-specific receptors, the functional activity of large populations of T cells can be redirected against defined targets including virally infected or cancer cells. The potential of therapeutic T cells to traffic to sites of disease, to expand and to persist after a single treatment remains a major advantage over the currently available immunotherapies that use monoclonal antibodies.

T cell responsiveness to an epitope is affected both by its affinity for the presenting MHC molecule and the affinity of the MHC-peptide complex for TCR. One limitation of cancer immunotherapy is that natural tumor antigens elicit relatively weak T cells responses, in part because high-affinity T cells are rendered tolerantly to these antigens. Scientists have reported that amino acid substitutions in a natural MHC class I-restricted tumor antigen that increase the stability of the MHC-peptide-TCR complex are significantly more potent than tumor vaccines. The improved immunity results from enhanced in vivo expansion of T cells specific for the natural tumor epitope. Hence, Creative Biolabs provides TCR-specificity assay with altering peptide ligands methods to test and optimize specificity of TCRs for interested antigens.
