Fig. 6. Uptake of HSA-Cy5, HSA Cy5-Hcy-TMX and HSA Cy5-Hcy-TMX-MTSL conjugates in cancer cells. A. In vitro cellular uptake of HSA-Cy5, HSA Cy5-Hcy-TMX and HSA Cy5-Hcy-TMX-MTSL by human glioblastoma multiforme T98G cells measured by flow cytometry. Blue colour: FACS analysis; numbers show percent cellular uptake of HSA conjugates. The data were normalized to non-treated cells (control). B. Representative fluorescence micrographs showing HSA conjugates in cells (DAPI nuclear stain, blue; Cy5-fluor 510 HSA labeled conjugates, red). Scale bar: 10/20 μm.
