costimulator Protocols

Category: Immunology: Mononuclear Cell Isolation Protocols: T-Cell Isolation Protocols

Protocols utilize T hybridomas to detect expression of peptide-MHC complexes, since these cells provide the most convenient, consistent, and flexible T cell readout systems for these purposes. If desired, antigen-specific T cell clones can be used in lieu of T hybridoma cells, but T cell clones often give poorer responses than T hybridomas to fixed APCs due to fixation-induced loss of costimulator function. - [Read Presenting Exogenous Antigen to T Cells Protocol]
