The Direct RNA Sequencing Kit (SQK-RNA004) is used to prepare and sequence native RNA without conversion to cDNA. Inputs include poly(A)-tailed RNA or total RNA, such as eukaryotic mRNA and viral RNA.

This kit upgrade includes increased sequencing output and improved modal raw read accuracy on our new RNA flow cell (FLO-MIN004RA and FLO-PRO004RA). The flow cell priming reagents are also included as part of the sequencing kit and have been reformulated to be compatible on the new RNA flow cell. Other updates include fuel fix technology, allowing users to run longer experiments without the need for fuel addition during the run.

Further considerations:

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 which currently provide the highest output per run.

Shipping and logistics:

Flow cells and kits are shipped together in an environmentally friendly temperature-controlled shipping box.

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.


The Direct RNA Sequencing Kit (SQK-RNA004) is used to prepare either poly(A)-tailed RNA or total RNA for sequencing by performing reverse transcription to synthesise a secondary complementary cDNA strand for stability to improve sequencing output. Sequencing adapters are then attached to the RNA-cDNA hybrid for sequencing.
