Fluorescence Imaging of Extracellular Potassium Ion Using Potassium Sensing Oligonucleotide

Fluorescence Imaging of Extracellular Potassium Ion Using Potassium Sensing Oligonucleotide

Potassium-sensing oligonucleotide, PSO, a conjugate of a quadruplex structure-forming oligonucleotide with a peptide incorporating a Förster Resonance Energy Transfer (FRET) chromophore pair, has been developed for fluorescent detection of potassium ion (K+) in aqueous medium. PSO 1 could be introdu...
