Isolation of T Cells from Synovial Membranes Protocol Protocol for isolation of T cells from synovial membranes. Includes: Initial Cell Isolation; Nonadherent Cell Isolation; Adherent Cell Isolation; Neuraminidase-Treated Sheep Red Blood Cells; Erythrocyte Lysing Solution; Balance Salt Solution (BSS).
Presenting Exogenous Antigen to T Cells Protocol 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.
T Cell Depletion by Cytotoxic Elimination Protocol Protocol describes removal of T cell subsets by cytotoxic elimination using CD-specific antibodies. Describes the complete removal of T cells from lymphocyte preparations based on the presence of the glycoprotein Thy-1 on the cell surface of T lymphocytes. Cytotoxic elimination is employed; however, Thy-1-specific antibodies are used rather than MHC class II-specific antibodies so that T cells are eliminated rather than B cells and accessory cells.
T Cell Enrichment By Nonadherence to Nylon Protocol Protocol describes a convenient, although imprecise, means of enriching T cells through removal of accessory and B cells; use of nylon wool is preferred if both of the latter subsets are to be removed, while Sephadex is used when the goal is primarily to remove accessory cells.
