便携式MicroRNA快速检测系统
Portable rapid microRNA detection system
摘要
Abstract
MicroRNA (miRNA) is closely related to the occurrence and development of certain diseases and can be used as a diagnostic marker.Conventional methods for the detection of miRNA are time-consuming and complex.Herein,a portable rapid miRNA detection system was designed.This system records the fluorescence intensity of the marker that is amplified via rolling circle amplification using a photoelectric detection technique,and analyzes the fluorescence data to obtain the changes in miRNA.Through our experiments,we observed that for reagent concentrations in the range 0.1-1 μmol,the linearity of the fluorescence intensity detected by the miRNA fluorescence detection equipment was less than ±5%,and the repeatability was ≥95%.Our roll amplification experiment involving the coronary heart disease diagnostic marker,miR-499,confirmed that the portable rapid miRNA detection system can detect miRNA quickly and effectively.关键词
