Description |
DFHBI is a small molecule that resembles the chromophore of green fluorescent protein (GFP). Spinach and DFHBI are essentially nonfluorescent when unbound, whereas the Spinach-DFHBI complex is brightly fluorescent both in vitro and in living cells. |

In Vitro |
These RNAs interact with DFHBI to produce a bluish-green fluorescence emission (501 nm) after excitation at 447 nm. Spinach and Spinach2 are RNA aptamers that can be used for the genetic encoding of fluorescent RNA. Spinach2 binds and activates the fluorescence of DFHBI, allowing the dynamic localizations of Spinach2-tagged RNAs to be imaged in live cells. The spectral properties of Spinach2 are limited by DFHBI, which produces fluorescence that is bluish-green and is not optimized for filters commonly used in fluorescence microscopes. Spinach and Spinach2 bind to DFHBI have fluorescence excitation maxima of 447 nm and peak fluorescence emission of 501 nm[1]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only. |
