Fluorogenic marker for instant live-cell membrane staining and imaging (2017-11-24)

A new organic-compound-based fluorogenic marker has been created for live-cell membrane staining. Unlike current commercial cell markers, the obtained fluorogenic marker does not fluoresce in the aquatic environment, but acquires fluorescence immediately after being placed in a nonpolar medium, for example, in the cell membrane. This property allows one to instantly stain cells without further washing out the unbound dye. This marker can be applied in fluorescence microscopy for live-cell imaging and flow cytometry.

    In nonpolar solvents, hydrophobic organic fluorophores often show bright fluorescence, whereas in polar media, they usually suffer from aggregation-caused quenching (ACQ). Here, we harnessed this solvatochromic behavior of a 1,3,5,7-tetramethyl-BODIPY derivative for cell staining and applied it to live-cell imaging and flow cytometry. As opposed to commercially available dyes, this BODIPY derivative showed excellent contrast immediately after staining and did not require any wash-off.
