Fig. 3. Intracellular localization of Syt IX in insulin-secreting cells. INS-1E cells and pancreatic ß-cells were double labelled with an antibody against insulin (revealed by FITC-conjugated antibody) together with the anti-Syt IX (detected by rhodamine-conjugated antibody). Images were obtained by confocal microscopy. The upper panels show the localization of insulin, the middle panels the position of Syt IX and the lower panels the superposition of the green and red channels.
