RT Journal Article T1 miR-122 direct detection in human serum by time-gated fluorescence imaging. A1 Garcia-Fernandez, Emilio A1 Gonzalez-Garcia, M Carmen A1 Pernagallo, Salvatore A1 Ruedas-Rama, Maria J A1 Fara, Mario A A1 López-Delgado, Francisco J A1 Dear, James W A1 Ilyine, Hugh A1 Ress, Cristina A1 Díaz-Mochón, Juan J A1 Orte, Angel AB A simple method for direct detection of microRNAs (miRs) in human serum without the use of polymerase amplification is presented, achieving low miR-122 concentrations and importantly, discerning effectively single-base sequence mutations. The method is based on the capture of target miRs with synthetic peptide nucleic acid oligomers, dynamic chemical labelling, separation with quaternary amine microplatforms and detection using time-gated fluorescence imaging.
