    摘要： The present teachings provide methods, compositions, and kits for reverse transcribing and amplifying small nucleic acids such as micro RNAs. High levels of multiplexing are provided by the use of a zip-coded stem-loop reverse transcription primer, along with a PCR-based pre-amplification reaction that comprises a zip-coded forward primer. Detector probes in downstream decoding PCRs can take advantage of the zip-code introduced by the stem-loop reverse transcription primer. In some embodiments, further amplification is achieved by cycling the reverse transcription reaction. The present teachings also provide compositions and kits useful for performing the reverse transcription and amplification reactions described herein.
