Description: GFP fluorophore mimic for imaging RNA in living cells; activated by binding Spinach2 and Broccoli aptamers
Chemical Name: (5Z)-5-[(3,5-Difluoro-4-hydroxyphenyl)methylene]-3,5-dihydro-2-methyl-3-(2,2,2-trifluoroethyl)-4H-imidazol-4-one
Purity: ≥98% (HPLC)
Biological Activity for DFHBI 1T
DFHBI 1T is a mimic of green fluorescent protein (GFP) fluorophore for imaging RNA in living cells. DFHBI 1T fluorescence is activated by binding to Spinach2 or Broccoli aptamers, also binds to Squash aptamer (Kd = 45 nM). DFHBI 1T exhibits peak excitation maxima of 482 nm and peak fluorescence emission of 505 nm when bound to Spinach2, enabling imaging with GFP filter cubes. Exhibits higher specific fluorescence and lower background fluorescence when bound to Spinach2 compared with Spinach2-DFHBI.
