Two‐Photon Fluorescent Probes for Acidic Vesicles in Live Cells and Tissue

Abstract

Move with the groove: Two-photon fluorescent pH probes and a two-photon lysotracker (AL1) can visualize acidic vesicles in live cells and living tissue for a long period of time without mistargeting and photobleaching problems. Using AL1, vesicles can be tracked in real time (see picture).
