Abstract
Fluorescent molecular probes have frequently been used to monitor lysosomal health, localization, abundance, and movement through the detection of acidic organelles and lysosomal enzyme activity. Flow cytometry technology provides rapid and accurate analysis of single cells (neurons) or particles (lysosomes) in suspension through laser detection. Herein, we describe how to detect lysosomes via LysoTrackerâ„¢ and Magic Red
Cathepsin Activity assays in iPSC-derived human neuron cultures by flow cytometry.
