Cellular senescence is a state of stable cell cycle arrest under which cells remain metabolically active, but no longer divide and do not respond to growth-promoting stimuli. It is triggered by a variety of cellular stressors, including environmental factors like ionizing radiation or exposure to chemotherapeutic drugs, oxidative stress, DNA damage, mitochondrial dysfunction, and oncogene activation. Senescence-Associated β-galactosidase (SA-β-gal), a result of altered lysosomal activity, is a hallmark of cellular senescence. Cellular Senescence Kit Red uses a fluorogenic beta-Gal substrate that readily enters into live cells, where it gets cleaved by SA-β-gal inside cells, generating strong red fluorescence. It provides higher sensitivity compared to X-gal staining, a colorimetric method widely available and used to detect Senescence-associated beta-galactosidase (SA-beta-gal) in senescent cells.

Components:
- 1 vial of lyophilized 100X Senescence Probe Red (beta-D-galactopyranoside)
(Store at < -15°C and minimize light exposure. All unused stock solutions should be stored as single-use aliquots and stored at < -15°C. Avoid repeated freeze-thaw cycles.) - 1 bottle (20 mL) of Senescence Assay Buffer (Store at < -15°C)
- 1 vial (100 μL) of DMSO (Store at < -15°C)
Required Materials Not Included:
- Buffer: PBS
Detection/Imaging Guidelines:
- Fluorescence microscope filter set: Cyanine3/TRITC filter set, recommend black wall/clear bottom plate
- Flow cytometry channel:
- Excitation: 488 nm laser
- Emission: 575/26 nm filter
- Instrument specification(s): PE channel
Assay Protocol:
This kit provides enough reagents for 100 tests. A test is defined as 100 µL of Senescence Probe Red working solution for up to 1x106 cells.- Preparation of stock solutions:
- Add 100 µL of DMSO into lyophilized 100X Senescence Probe Red and mix well.
Note: Store the unused Senescence Probe Red stock solution at -20°C in single use aliquots.
- Add 100 µL of DMSO into lyophilized 100X Senescence Probe Red and mix well.
- Preparation of working solutions:
- Dilute 10 µL of 100X Senescence Probe Red stock solution with 1 mL of Senescence Assay Buffer to make Senescence Probe Red working solution. This can be used for 10 tests; each test will need 100 µL Senescence Probe Red working solution.
Note: Senescence Probe Red working solution should be used promptly.
- Dilute 10 µL of 100X Senescence Probe Red stock solution with 1 mL of Senescence Assay Buffer to make Senescence Probe Red working solution. This can be used for 10 tests; each test will need 100 µL Senescence Probe Red working solution.
Experimental Protocol:
-
Treat your cell samples under desired experimental conditions.Note: For selectively tracking β-Gal in live cells, cells can be treated with Bafilomycin A1 for blocking endogenous β-Gal. Optimum concentration of Bafilomycin A1 may vary depending on cell type (suggested range is 100 nM-10 mM).
-
Gently wash the cells with Cell Staining Buffer (Cat. No. 420201) or PBS.
-
Add 100 µL Senescence Probe Red working solution for up to 1x106 cells (for higher cell amounts, scale up accordingly). And incubate the samples at 37°C incubator for 15-45 minutes.
-
Gently remove the Senescence Probe Red solution from cells and wash twice with Cell Staining Buffer (Cat. No. 420201) or PBS.
-
Analyze samples: For flow cytometry, resuspend the cells in the Senescence Assay Buffer and monitor the fluorescence intensity on a flow cytometer using a 575/26 nm filter (PE channel). For live cell imaging, observe cells with inverted fluorescence microscope using a Cyanine3/TRITC filter set.
