A_Lysosome_Probe_NIR_080223
Live cell fluorescence imaging of RAW264.7 cells starved with serum-free and glucose-free media for 4 hours to induce lysosomal activity and treated with 200 nM Bafilomycin (left) or left untreated (right). Cells were then stained with Lysosome Probe NIR (magenta) and nuclei were stained with Hoechst 33342 (blue). Images were captured using a 60X objective. Scale bar: 10 µm

Description

Lysosomes are cellular organelles involved in degrading cellular debris during autophagy, as well endocytosed material. Defects in lysosomal function are related to neurodegenerative disorders, cancers, and aging-related diseases. Lysosome Probe NIR labels lysosomes in live cells and selectively accumulates in lysosomes via the lysosomal pH gradient. Fluorescence is greatly enhanced upon entry into lysosomes. Its photostability and excellent cellular retention makes this probe particularly useful for live cell imaging applications, as well as for flow cytometry.

Application Notes

Component:
20 μL of 500X Lysosome Probe NIR (-20°C, protected from light, avoid freeze/thaw cycles)

Required Materials Not Included:
Buffer: PBS, phenol-free media, or HBSS 

Detection/Imaging Guidelines:
Ex/Em = 636/650 nm 
Fluorescence microscope filter set: Cyanine5
Flow cytometry channel: APC channel 

Assay Protocol:

  1. Thaw the 500X Lysosome Probe and allow it to reach room temperature.
  2. Prepare lysosome staining solution by diluting the Lysosome Probe 1:500 in your buffer of choice.
    Note: Probe concentration may need to be adjusted according to cell type and assay conditions.
  3. Optional: Include live-cell nuclear counterstain such as CytoPhase™ Violet (cat# 425701) or Hoechst 33342.
  4. Add an equal volume of Lysosome Staining solution to cell culture media.
  5. Incubate the cells at 37°C for 30 minutes.
  6. Wash cells by twice with PBS or HBSS. If cells are in suspension, spin down and resuspend in buffer of choice.
  7. Add desired volume of PBS or HBSS to cells for observation.
  8. Proceed immediately to analysis.
