We developed a method of video-rate bioluminescence imaging to visualize proteins secreted from living cells. A protein of interest was fused to Gaussia luciferase (GLase), and the luminescence signals of secreted GLase with coelenterazine (luciferin) were visualized at a video-rate of 30-500 ms/frame by using a water-cooled EM-CCD camera. We established a subclonal rat INS-1E cell line, named iGL cells, stably expressing the fusion protein of insulin and GLase (Insulin-GLase). By stimulation with high glucose, 3D-cultured i
