Center for AIDS Health Disparities Research Department of Biochemistry and Cancer Biology, Meharry Medical College, 3Kalinga Institute of Industrial Technology University This report describes a fast and reliable method for validating mRNA targets of cellular miRNAs. The method uses synthetic biotinylated Locked Nucleic Acid (LNA)-based miRNA mimics to capture target mRNA. Subsequently, streptavidin-coated magnetic beads are employed to pulldown the target mRNA for quantification by qPCR polymerase chain reaction.
