AlDeSense AM
AlDeSense AM is a cell-permeable ALDH1A1-selective fluorescent reporter. AlDeSense AM is oxidized by ALDH1A1, which eliminates photoinduced electron transfer quenching and enhances the fluorescent signal. AlDeSense AM can be used to detect cells with cancer stem cell properties, as well as to monitor the plasticity of cancer stem cells in cell culture systems and animal models. AlDeSense AM is applicable to the study of cancers associated with cancer stem cells, including chronic myeloid leukemia, melanoma, and breast cancer.

AlDeSense AM (1.5-2 μM; 30 min) selectively labels human chronic myeloid leukemia K562 cells with active ALDH1A1, which correspond to the CD34+/CD38−/CD133+ leukemia stem cell population[1].
AlDeSense AM (2 μM; 1 h) detects elevated ALDH1A1 activity in MDA-MB-231 breast cancer mammospheres (cancer stem cell-enriched), and the fluorescent signal decreases as the mammospheres differentiate over 36 h[1].
The fluorescence signal of AlDeSense AM (2 μM; 1 h) in CSC-enriched B16F0 e-CSC is 11.3-fold higher than that in non-CSC B16F0 cells, confirming elevated ALDH1A1 activity in e-CSC[1].

-
Cell Line:K562 human chronic myeloid leukemia cells
-
Concentration:1.5 μM (flow cytometry staining); 2 μM (confocal imaging staining)
-
Incubation Time:30 min at room temperature (confocal imaging staining)
-
Result:Identified a population of brightly fluorescent cells corresponding to the CD34+/CD38-/CD133+ leukemic stem cell profile.
Showed a small population of highly fluorescent cells via confocal imaging.
Completely abolished the fluorescence signal after ALDH1A1 siRNA knockdown.

Incubation Time:1 h at room temperature (at 1, 6, 12, 24, 36 h time points during differentiation)
-
Result:Exhibited 3-fold brighter fluorescence in freshly isolated mammospheres compared to control-stained mammospheres.
Gradually decreased fluorescence signal over 36 h of differentiation.

Result:Produced a mean fluorescence signal of ~1×1011 a.u.
in lungs with e-CSC metastases.
Showed a significantly higher mean fluorescence signal (~1×1011 a.u.) than the ~7×1010 a.u.
measured in lungs with non-CSC metastases.
Demonstrated significantly higher fluorescence in e-CSC metastases than e-CSC metastases treated with Ctrl-AlDeSense AM.
