Reverse Transcription (RT) and qPCR can be achieved in a One-Step or in a Two-Step approach.
A Two-Step reaction consists in distinct RT and qPCR reactions (using MasterMix or Core Kit).
A One-Step approach consists in a single tube reaction combining all the necessary reagents to amplify DNA from a RNA based sample. The One-Step Takyon™ MasterMix contains the EuroscriptII RT which delivers highly robust performance on classical mRNAs, small RNAs and viral RNAs.
One-step approach is a simple process limiting the contamination risks without compromising performances; thanks to the robust reverse transcriptase and the additive improving performance on difficult templates e.g. viral RNAs, FFPE…
Some one-step kits are available as catalogue references but any other Takyon™ dTTP Master Mix for qPCR assays can easily be converted into a one-step RT-qPCR kit by using the Takyon™ One-Step kit converter.
