Figure Lengend Snippet: Flow cytometry analysis of targeted contrast agent-labeled cancer cells and peripheral blood mononuclear cells (PBMCs). Suspensions of 1:1000 IGROV-1 ovarian cancer cells to PBMCs were incubated (a) without and (b) with OTL38. (c) Different FR expressing cancer cell lines and PBMCs incubated with OTL38 compared with unlabeled PBMCs, cells, and reference μspheres (JGLI). Labeled cell threshold (black line) and NIR-DiFC detection threshold (red line) are shown, and percentages of cell populations above the respective threshold are indicated in the same color. Suspensions of 1:1000 LLC lung cancer to PBMCs were incubated (d) without and (e) with VGT-309. (f) Different cathepsin-expressing cancer cell lines and PBMCs incubated with VGT-309 compared with unlabeled PBMCs, cells, and reference μ spheres (JGLI). Labeled cell threshold (black line) and NIR-DiFC detection threshold (red line) are shown, and percentages of cell populations above the respective threshold are indicated in the same color.
