Lysosomal Function Analysis

Why is Lysosomal Function Important?

The lysosome has been revealed to be an important organelle with a complex role in nutrient sensing and multifaceted signaling. Its importance has been emphasized in research fields as diverse as a neurological disease, cancer, immunity, and senescence.

Recent research reveals that lysosome acidification declines in neurons well before extracellular amyloid deposition, thus lysosomal function is now a hot topic in Alzheimer's disease research.


Lysosomal pH Detection Dye: pHLys Red

pHLys Red has a high sensitivity to lysosomal pH change with more precise localization, which allows slight pH changes to be detected in physiological conditions like the early phase of the disease


Lysosomal Mass Detection Dye: LysoPrime Green, Deep Red

Dojindo’s LysoPrime Green / Deep Red more precisely detects lysosomal mass due to their unique specificity for lysosomes, and retention independent of lysosomal pH. In addition, the retention time of the dyes in lysosomes has been extended, allowing data to be acquired over time.

Application data


Endocytic vesicles were labeled by ECGreen and the lysosomal mass and pH were detected separately with LysoPrime Deep Red and pHLys Red. Co-staining with ECGreen and Lysosomal dyes showed the inhibition of endocytic vesicle-fusion induced by Bafilmycin A1.


We tried the simultaneous detection of lysosomal and mitochondrial dysfunction in Hela cells treated with CCCP or Antimycin (AN). CCCP and AN are well-known inducers of mitochondrial ROS regarding loss of mitochondrial membrane potential. Recent research showed the result that CCCP induces not only mitochondrial ROS but also lysosomal neutralization. To detect mitochondrial ROS, HeLa cells were labeled by mtSOX Deep Red - Mitochondrial Superoxide Detection, and the lysosomal mass and pH were detected separately with LysoPrime Green and pHLys Red. Co-staining with mtSOX and Lysosomal dyes demonstrated that CCCP causes lysosomal neutralization and mitochondrial ROS induction at the same time.
