Hi everybody, we have a BD FACS-Vantage and have tried to measure Ca-fluxes in GFP overexpressing cells. The cells used are a low-adherent tumor cell line and were detached by little mechanical force (tapping the flask). We used INDO as the Ca-dependent fluorescent dye. Unfortenately, we had bad luck. Even with ionomycin, we did not get a Ca response. Has somebody experience with this combination (GFP INDO) and can help us? A second question: Who knows a flow cytometry company working about blood homeostasis (platelet activation ...) in Europe?
