Selective miRNA quantitation with high-temperature thermal gel electrophoresis.

ABSTRACT: MicroRNAs (miRNAs) are short non-coding RNAs that control gene expression and correlate to the prognosis of numerous diseases. To support research efforts elucidating the roles of miRNAs in pathogenesis, rapid and inexpensive analytical methods are required to quantify miRNAs from biological samples. The challenge of developing new analyses with these time and cost constraints is compounded by the short sequence lengths and high degrees of homology between miRNAs that hinder detection selectivity. This report describes the development of a high-temperature thermal gel electrophoresis (TGE) method to rapidly quantify miRNAs with single-nucleotide resolution using low-cost microfluidic devices. Fluorescent probes were designed for three miRNAs that differed in sequence by one or two nucleoti
