PRESENTATION: Lyophilized dye
STORAGE CONDITIONS: Stable in the dark for 2 year at -20 ºC.
QUALITY ASSURANCE: Products are analyzed by 1H NMR and LC-MS and provided at purity of >95% by HPLC.
USAGE STATEMENT: This product is intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals. Due to the highly specific nature of fluorophores and aptamers, we cannot predict or be held responsible with respect to how LucernaTM products will behave in its customers’ systems. Researchers using LucernaTM products should conduct optimization studies to achieve the optimal result possible for their intended application.
Figure 1. HEK293T cells were transfected with either 5S-control aptamer or 5S-SpinachTM plasmids and incubated with 20 µM DFHBI. Images are phase overlay with Hoechst-stained nuclei (blue) and SpinachTM fluorescence (green).
Figure 2. SpinachTM RNA robustly activates the fluorescence of DFHBI. Each tube contained the indicated solution and was irradiated at 465 nm.
