Measuring pH in insulin secretory granules by phasor-based fluorescence lifetime imaging of a genetically encoded sensor
Abstract It is widely accepted that the pH of insulin granules is acidic, and that its active regulation during granule maturation plays a role in the process of insulin secretion by β-cells. Yet, a calibrated measurement of the absolute granule pH with organelle specificity is still lacking. To tac...
