Figure 1From: A novel flow cytometric assay for measurement of In Vivo pulmonary neutrophil phagocytosisStaining of S. pneumoniae with CFDA/SE. Forward vs. side scatter plots of Unlabeled (A) and CFDA/SE labeled (B) type 3 Streptococcus pneumoniae are indistinguishable. Histograms of cell counts vs. CFSE staining (the fluorescent intracellular form of the dye), however, clearly demonstrate the shift in fluorescence between unlabeled (C) and CFDA/SE labeled (D) pneumococci.Back to article page
