WebFeb 28, 2024 · To ensure the expression of HLA-A2 on T2 cells, expression of HLA-A2 on the surface of T2/AFP 158–166 cells was tested by flow cytometry. Antigen peptide AFP 158–166 at a concentration of 20 and 40 µg/mL was incubated with T2 cells. Results showed that 7.8% T2 cells expressed HLA-A2 molecules without being pulsed with AFP … MHC multimers are oligomeric forms of MHC molecules, designed to identify and isolate T-cells with high affinity to specific antigens amid a large group of unrelated T-cells. Multimers generally range in size from dimers to octamers; however, some companies use even higher quantities of MHC … See more Since T-cell receptors have a low affinity for their MHC counterparts, it was historically problematic to label T cells effectively using single MHC-T-cell interactions. However, in 1996 it was proposed by John Altman to use a … See more MHC tetramer MHC tetramers consist of four MHC molecules, a tetramerization agent and a fluorescently labeled protein (usually streptavidin). Streptavidins have also been generated with 6 or 12 binding sites for MHC. MHC … See more The most commonly used MHC multimers are tetramers. These are typically produced by biotinylating soluble MHC monomers, which are typically produced recombinantly in … See more MHC multimers allow for a previously unattainable level of specificity in antigen-specific T-cell detection and isolation. This ability gives rise to several clinical applications.
