Improved methods that increase the specificity and sensitivity of detection of small RNAs, including miRNAs, using oligonucleotide primers and nucleic acid amplification, are provided. Reaction conditions that result in preferential decrease in cDNA synthesis of RNAs other than the small RNA molecules targeted for detection during miRNA tailing and reverse transcription reactions are described. Using these reaction conditions greater sensitivity and specificity of amplification of small RNAs including miRNAs is achieved.
