20150056623 | Oligonucleotide Primer with Omega Structure for Detecting Short-Chain RNAs and Use Thereof - Disclosed are an oligonucleotide primer with an omega structure for detecting short-chain RNAs and the use thereof. The primer from the 5′ end to the 3′ end sequentially is: a PCR primer target region of 20-30 bases, a variable coding region of 0-50 bases, an omega stem-loop, a probe spacer of at least one base and a probe region of 4-11 bases. The length of the stem of the omega stem-loop is 4-12 paired bases, and the length of the loop of the omega stem-loop is 3-20 unpaired bases. | 02-26-2015 |
