CD25 expression in CD4⁺CD25^dim and CD4⁺CD25^bright following magnetic bead purification^a

CD4⁺CD25^dim		CD4⁺CD25^bright

a CD25 surface expression and PGE₂-mediated modulation of CD25 in CD4⁺ PBL. Data summarize (n = 8) the CD25 expression of CD4⁺CD25^dim and CD4⁺CD25^bright T cell populations following cell purification (Miltenyi Treg Cell Isolation kit). Results are expressed as percentage of CD25 expression within the CD4⁺ population. Values in parentheses indicate the mean fluorescence intensity (MFI) of CD25 expression based on density plot analysis.
