Fig 5. Possible interaction of Ca2+-sensitive dyes with Zn2+ in C6 glioma cells.

Fig 5

(A) C6 glioma cells were loaded with Rhod-2 in the presence of CaCl2, followed by determination of the fluorescence intensity in either the presence or absence of ZnCl2 every 1 min. (B) Cells were loaded with either Fluo-3 or FluoZin-3 in the presence of CaCl2, followed by determination of the fluorescence intensity in the presence of ZnCl2 every 1 min. Values are the mean±S.E. of the rate of fluorescence change in 3 different experiments.
