Sequence RNA molecules directly and preserve base modifications

 Includes a Flow Cell Priming Kit
$599.00

Information

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

Please note that to use this kit, you will need to purchase additional 3rd party reagents: see the "3rd Party Materials" tab for more detail.

Further considerations:

The direct RNA sequencing chemistry is new and both accuracy and throughput will continue to improve with future 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 output per run.

Shipping and logistics:

Flow cells and kits are shipped together at 2–8°C.

Upon receipt, please place the right product in the right long-term storage location.

Products are shipped to customers within the USA and EU Monday to Thursday. Shipments to Canada, Norway, Korea and Japan are expedited Monday to Wednesday; with Australia and New Zealand leaving our warehouses on a Friday. Shipments to the rest of the world are made on Mondays to allow the full working week for packages to arrive.

The delivery charges are calculated when a quote is raised or during checkout. Once an order is made, the delivery ID and delivery information can be tracked in the Store.

Workflow

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 output.
