Figure Lengend Snippet: IL-7 co-localizes with the recycling endosome marker, Rab11, in cytokine pulsed lymphocytes. Cytospin preparations of PBMC were immunostained for IL-7 and Rab11 after 1 hour of incubation with rIL-7 (100 ng/ml) as described in the methods. Representative image of one lymphocyte showing (A) IL-7 (red), (B) Rab11 (green), and (C) DAPI (blue). (D) Merged image indicates evidence of co-localization of fluorescent signals. (E) The correlation coefficients (Pearson’s R value, and Spearman’s rank correlation value(ρ) for pixel co-localization of IL-7 and Rab11 signal in 18 cells is shown and plotted from the cell with the least correlation to the cell with the greatest correlation. Cells that were not pulsed with IL-7 and antibody isotype control stains were used as negative controls and did not demonstrate evidence of staining (not shown).
Article Snippet: Next, the slides were hard-mounted in Vectashild™ with DAPI and examined by an automated epi-fluorescent microscope (EVOS ® FL, Life Technologies).
