I'm interested in measuring Tregs (FoxP3) and Th1, Th2 and Th17 subpopulations trough intracitoplasmatic interleukin procedure (IFN-g, IL-4 and IL-17) after stimulation in the same tube, so does anybody know if there is any inconvinient in measuring FoxP3 after the corresponding 6h cell stimulation with PMA, ionomicine and Brefeldine?
