What percentage of IL-17 positive cells are expected to be positive in Th17-polarized cells in flow cytometry?
Day-1: Coating anti-CD3 and anti-CD28
Day 0: Seeding of purified CD4 cells + Cytokine cocktail for Th17 polarization (IL-6, IL-23, IL-1beta) + Anti-IL-4 & Anti-IFN-gamma
Day 5: PMA+ Ionomycin stimulation
IL-17 staining

How can we differentiate polarization and IL-17 staining issues in case of
