Figure S2. Reporter assay using mouse and human MAIT cell reporters.

(A, B, C, D) Representative histograms of GFP-reporter activities of human (A, C) and mouse (B, D) MAIT cell lines. Mouse MAIT cell line 12F12 or human MAIT cell line 4L4T were cocultured with MR1-overexpressing antigen-presenting cells in the presence of 9 ml of indicated homogenates. (A, B) As negative and positive controls, Ac-6-FP (100 mM) or 5-OP-RU (10 nM) were added during the co-culture, respectively.
