In vitro t cell cytotoxicity assay
Did you know?
WebCytotoxicity is the primary function of CD8 + T-cells, also called cytotoxic CD8 + T lymphocytes (or CTLs). Quantification of this capacity is of major importance in diagnostic and research tools. While phenotypic characterization of CTLs is frequent and easily performed, their function is indeed more difficult to assess. WebCytotoxicity assays measure the ability of cytotoxic compounds to cause cell damage or cell death. Cytotoxicity assays are widely used in fundamental research and drug discovery to screen libraries for toxic compounds. In drug discovery, cytotoxicity is a critical endpoint when evaluating the fate and effects of a compound.
WebBut eventually CAR T cells or TCRs will need to be tested in vitro with primary human tissues. Potential over-activation or off-target effects are part of early development and lead optimization of these therapies. Charles River has developed assays to test T cell therapies on primary human tissues, to assess cytotoxicity and activation. WebOct 20, 2024 · A simple co-culture assay that can assess anti-tumour T-cell cytotoxicity via luminescence and flow cytometry has been created. Researchers have developed a simple co-culture assay that can be used with to assess anti-tumour CD8+ T-cell cytotoxicity via luminescence and multicolour flow cytometry.
