Amino Bodipy-Based Blue Fluorescent Probes For Aldehyde Dehydrogenase 1-Expressing Cells

Aldehyde dehydrogenase 1 (ALDH1) plays an important role as a stem cell marker. In the field of stem cell biology, a green fluorescent ALDH1 probe has been principally used, but there is a need for more options in probe color. We designed and synthesized two blue fluorescent ALDH1 probes using 8-amino BODIPY and aminomethylbenzaldehyde. These probes can be simultaneously used with other color probes. Here, we demonstrate successful examples of the simultaneous use of these probes with green fluorescent protein.
