Should I use Omniscript or Sensiscript for reverse transcription of low-copy mRNA?

Omniscript and Sensiscript RT are recombinant RTs optimized for use with different amounts of starting RNA. Both are sensitive for detecting low-copy mRNA species. The enzyme of choice depends on the total amount of RNA in the sample (including any carrier RNA present), regardless of the specific target RNA copy number. For standard reverse transcription, with 50 ng to 2 µg of RNA per reaction, Omniscript RT provides optimal results for both high- and low-copy mRNA species. Sensiscript RT is optimized for use with very small amounts of RNA (<50 ng), such as for single-cell RT-PCR or analysis of small biopsies.
