Prior to fixation and antibody incubation, we recommend adding a fixable viability dye such as the Ghost Dye Violet 510 Fixable Viability Dye to enable identification and exclusion of dead cells from analysis. This panel can be combined with peptide-MHC tetramer staining to identify antigen-specific cells. Tetramer staining is often performed on live cells. If tetramer staining is desired, we recommend comparing activity of the reagent in live cell staining vs. the recommended protocol for the panel. If there is not a significant difference between the two conditions, the tetramer can be included in the antibody panel staining mix. If there is significant loss of activity following fixation and permeabilization, tetramer staining should be done on live cells prior to fixation and permeabilization. Gating strategy for observing progenitor exhausted CD8+ T cells: If a fixable viability dye was used, first gate on viable cells. Next, gate on lymphocytes based on forward scatter and side scatter. Cytotoxic T cells are the CD3+CD8+ cells within the lymphocyte gate. Next, observe TCF1 and PD-1 expression on the cytotoxic T cells. Cytotoxic T cells that are TCF1+PD-1+ are exhausted progenitor cells and are expected to be mostly negative for Granzyme B expression. Cytotoxic T cells that are TCF1-PD-1+ are differentiated cells with effector potential and are expected to be mostly positive for expression of Granzyme B.\n\u003cb\u003eStorage\u003c\/b\u003e\nPD-1 (Intracellular Domain) (D7D5W) XP ® Rabbit mAb (Alexa Fluor ® 488 Conjugate), TCF1\/TCF7 (C63D9) Rabbit mAb (PE Conjugate), and Granzyme B (D2H2F) Rabbit mAb (Alexa Fluor ® 647 Conjugate) are supplied in PBS (pH 7.2), less than 0.1% sodium azide and 2 mg\/ml BSA.
