Information
This kit is highly recommended for users who:
- have a limited amount of input material
- want to optimise their sequencing experiment for throughput
- would like to identify and quantify full-length transcripts
- are interested in differential gene expression
- want to characterise and quantify isoforms, splice variants and fusion transcripts
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.
The PCR-cDNA Sequencing Kit is used to prepare cDNA for nanopore sequencing from an input of as low as 1 ng poly-A+ RNA. Users who do not have poly-A+ enriched RNA can use 50 ng of total RNA but additional optimisation may be required.
Taking full-length poly-A+ RNA, complementary strand synthesis and strand switching are performed using kit-supplied oligonucleotides. dscDNA is then generated by PCR amplification using primers that contain 5’ tags which facilitate the ligase-free attachment of Rapid Sequencing Adapters.

Further considerations
The PCR-cDNA Barcoding Kit (SQK-PCB109) can be used instead of the PCR-cDNA Sequencing Kit to multiplex up to 12 different RNA samples into a single flow cell.
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.
Workflow
Taking full-length PolyA+ RNA, complementary strand synthesis and strand switching are performed using kit-supplied oligonucleotides. dscDNA is then generated by PCR amplification using primers that contain 5’ tags which facilitate the ligase-free attachment of Rapid Sequencing Adapters.

Protocols
