ALDEFLUOR™ Kit for ALDH Assays
Identification, Evaluation and Isolation of Normal and Cancer Stem & Progenitor Cells
How ALDEFLUOR™ Detects Normal and Cancer Progenitor Cells
The ALDEFLUOR™ kit contains BODIPY-aminoacetaldehyde (BAAA), a fluorescent non-toxic substrate for ALDH, which freely diffuses into intact and viable cells. In the presence of ALDH, BAAA is converted into BODIPY-aminoacetate (BAA), a negatively charged product that is retained inside the cells. Intracellular accumulation of BAA leads to increased fluorescence, and these ALDH-bright (ALDHbr) cells can be analyzed with flow cytometry. Watch this video to learn more about how ALDEFLUOR™ works.
Why Use ALDEFLUOR™?
- Detect viable normal or cancer progenitor cells based on ALDH activity. No antibody staining required.
- Can be used with multiple cell types and species.
- Identifies only viable cells with an intact cell membrane. Compatible with immunophenotyping.
- Has supported more than 1000 peer-reviewed publications.
- Simple protocol with highly reproducible results. Compatible with standard cell sorters or analyzers.

Optimizing ALDEFLUOR™ for Various Tissue Types
ALDEFLUOR™ was initially developed and optimized for the detection of ALDHbr hematopoietic stem and progenitor cells in human blood and bone marrow. Since then it has also been shown to detect normal and neoplastic cells in many other tissue types (including breast, colon, lung, pancreas, and thyroid) as well as cancer cell lines. Optimizing the ALDEFLUOR™ protocol to your tissue type of interest can dramatically increase the fluorescence intensity, thereby optimizing the assay performance. Watch this video to see an example of how our scientists increased the fluorescence intensity of ALDHbr cells in mammary tissue and learn how you can modify the protocol to fit your research needs.
