DIR2s-Apt fluorescent RNA aptamer
DIR2s-Apt is a fluorescent RNA aptamer comprising a short ribonucleotide sequence that exhibits fluorescence upon binding to a specific fluorophore.
Characterization
The DIR2s-Apt fluorescent RNA aptamer was described by Tan et al. (2017).
The DIR2s-Apt folding prediction as simulated by [http://www.nupack.org// NUPACK] is shown below.
Usage and Biology
It is usually used in live-cell imaging, however it can also be used in vitro. DIR2-Apt can be used for visualisation by gene fusion to the target of interest. Its fluorescent colour depends on the fluorophore it binds to. It can bind to DIR ( dimethylindole red) derivatives to give a red colour and OTB (oxazole thiazole blue) derivatives to give a blue colour. The emission spectra also depends on the bound fluorophore. The DIR-Profluorophore has an excitation wavelength of 600 (nm) and an emission wavelength of 658 (nm). The OTB-SO3fluorophore has an excitation wavelength of 380 (nm) and an emission wavelength of 421 (nm).
