Cover Story: Loss of lysosomal membrane integrity affects cellular functions and can induce cell death via the release of lysosomal hydrolases. Several drugs used clinically have the ability to destabilize the lysosome, which can be utilized as a treatment strategy. The expanding interest for lysosomal function has emphasized the need for assays that follow lysosomal damage and detect minor damage that does not inevitably cause cell death. The weak base acridine orange accumulates in the acidic environment of lysosomes but is released upon lysosomal damage. In this protocol, we present a high-throughput microplate reader-based method to follow destabilization of the lysosomal membrane in real time using acridine orange. This protocol can easily be adopted for patient samples since the number of cells per sample is low and the time for analysis is short. View this paper

Real-Time Monitoring of Lysosomal Membrane Permeabilization Using Acridine Orange

  • Ida Eriksson,
  • Linda Vainikka,
  • Hans Lennart Persson and
  • Karin Öllinger

Loss of lysosomal membrane integrity results in leakage of lysosomal hydrolases to the cytosol which might harm cell function and induce cell death. Destabilization of lysosomes often precede apoptotic or necrotic cell death and occur during both phy...
