This kit is highly recommended for users who:
- would like to remove RT or PCR bias
- have transcripts that are difficult to reverse transcribe
- are exploring attributes of native RNA such as modified bases

The Direct RNA Sequencing kit (SQK-RNA002) is used to prepare any RNA with a 3’ polyA tail for 1D sequencing on the Oxford Nanopore sequencing devices. Possible input RNA includes eukaryotic mRNA, viral RNA with a polyA tail, or any RNA prepared with a polyA-tailing kit. For RNA without a polyA tail, users can follow simple instructions to design their own custom adapter to ligate a specific terminal 3’ sequence like the 3’ of tRNA or 16S rRNA. The kit requires 500 ng of input RNA.
In contrast to cDNA sequencing protocols, which are used to prepare cDNA copies of RNA for sequencing, the Direct RNA kit is used to prepare RNA itself for sequencing. In Direct RNA Sequencing, only the native RNA passes through the nanopore sensor thus the read length reflects the length of the RNA molecules in the sample.
The Direct RNA Sequencing protocol contains an optional (but recommended) reverse transcription step and though the cDNA strand generated in this step is not sequenced, it significantly improves sequencing throughput.
The Direct RNA Sequencing kit is new and both accuracy and throughput will continue to improve with coming kit versions. In applications where Direct RNA sequencing’s key advantages (detection of modified bases and reduced bias) are not important, users may consider one of Oxford Nanopore’s cDNA kits because they currently provide the highest throughput per run.
Oxford Nanopore Technologies deem the useful life of the product to be 3 months from receipt by the customer.
