Flow cytometry analysis of TCR V alpha 12.1 showing positive staining in the membrane of peripheral blood mononuclear cells compared to an isotype control (blue). Human blood was collected and combined with a hydrophilic polysaccharide then centrifuged. Samples were transferred to a conical tube and washed with PBS. 50 ul of cell solution was added to each tube at a dilution of 2x10^7 cells/ml and 50 ul of isotype control and ab171107 at 1:20 added. Cells were incubated for 30 min at 4^oC and washed with a cell buffer and incubated with a DyLight 488-conjugated goat anti-mouse IgG (H+L) secondary for 30 min at 4^oC in the dark. FACS analysis was performed using 400 ul of cell buffer.
