Example of the analysis of expression levels of peptide/MHC complexes tagged with fusion-fluorescent proteins on transduced DCs. Naive CD4+ T cells (T) were mixed with AbIi- DCs (DC) expressing agonist AbPCCVA-CFP and null AbEp-YFP complexes. (A–D) A single 2D optical section in the center of the cell conjugate. (A) A DIC image. (B) AbEp-YFP only (green). (C) AbPCCVA-CFP only (blue). (D) AbPCCVA-YFP and AbEp-CFP overlay. (B' and C' ) Fluorescence images are color coded according to the scale on the right. (D'' ) Intensity profile is taken from nondeconvolved D'' image along the red line. The histogram shows the fluorescence intensity of the cell membrane. The green solid line corresponds to the intensity of null AbEp complexes, and the blue dashed line corresponds to the intensity of the agonist AbPCCVA complexes.
