Will this work for micro RNA templates?

Yes, PCRBIO 1-Step Go RT-PCR Kit can be used for micro RNA templates. Although we do no sell dedicated kits, all of our RTases can be used for miRNA quantification and analysis.

We advise that you use one of the two following approaches:

  • Use universal RT primers and add poly(A) or poly(U) tails (e.g. by poly(U)-polymerase), followed by cDNA synthesis using universal primers1,2.
  • Use specific RT primers and omit the tailing step1,3-5.

If you are unfamiliar with the specifics of those approaches, please refer to the reference list below, which serve as a guideline.
