Abstract
Fluorescence resonance energy transfer (FRET)-based live-cell imaging and genetically encoded biosensors are widely used to study biochemical processes in living cells. However, there remains a gap in robust analytical methods for examining complex processes like endosomal trafficking. In this study, we introduce two advanced tools—EasyFRET and EndoAna—specifically designed for FRET image analysis, along with two novel potassium biosensors, GalT-KIRIN and KIRIN-Lamp1, targeted to endosomes and lysosomes, respectively. Together, these tools establish a comprehensive workflow for investigating potassium signaling, which plays a critical role in cellular homeostasis and various biological functions. Our live-cell imaging results demonstrate that EasyFRET and EndoAna provide efficient and reliable FRET image analysis, while the potassium indicators offer valuable insights into potassium dynamics within the endosomal trafficking system.
