Description
Barcoding or multiplexing is useful when the amount of data required per sample is less than the total amount of data that can be generated from a single flow cell: it allows a user to pool multiple samples and sequence them together, making more efficient use of the flow cell.
The PCR-cDNA Barcoding Kit is used to prepare cDNA for nanopore sequencing for up to 12 samples, 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. The kit contains 12 primer pairs which are used to generate and then amplify double-stranded cDNA by PCR amplification: each primer pair contains a barcode and 5’ tag which facilitates the ligase-free attachment of Rapid Sequencing Adapters. Amplified and barcoded samples are then pooled together, and Rapid Sequencing Adapters are added to the pooled mix.
Shipping and logistics
Flow cells and kits are shipped together in a temperature-controlled shipping box with gel ice packs. Ice packs are stored at 2-8° C, and -20° C ice packs are added to the top of the box (but not in direct contact with product) to maintain the integrity of the shipment.
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.
Oxford Nanopore Technologies deem the useful life of the product to be 3 months from receipt by the customer.
