Abstract

Micro-RNA has attracted much attention as a biomarker for disease progression and malignancy. A compact, simple, rapid, and highly sensitive method is required to perform simple genetic analyses, such as point-of-care testing (POCT), at the clinic or bedside. Nucleic acid sequence-based amplification (NASBA) is a specific amplification method for a single-stranded RNA fragment that is useful for the highly sensitive detection of miRNAs. In this work, we developed a novel miRNA analytical system for POCT by combining the NASBA and chemiluminescence methods. Because the NASBA reaction is conducted at a constant temperature (41°C) and detection by chemiluminescence reaction does not require a light source, these methods could be combined to amplify 100 ng/assay miRNA. This combined miRNA detection method could be useful for the future development of compact POCT systems.
