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.
Multiplexing samples onto one flow cell can reduce the cost per sample for a user. Below are some worked examples:
|No barcodes||6 barcodes||12 barcodes||24 barcodes|
|Flow cell price||$500||$500||$500||$500|
|Price per sample||$599||$104||$54||$28|
The PCR-cDNA Barcoding Kit is used to prepare cDNA for nanopore sequencing for up to 24 samples, from an input of as low as 4 ng polyadenylated RNA. Users who do not have polyadenylated enriched RNA can use 200 ng of total RNA but additional optimisation may be required.
The protocol uses a strand switching method to select for full length transcripts, allowing the identification of splice variants, with the incorporation of unique molecular identifiers (UMI) during this step. Taking full-length polyadenylated RNA, complementary strand synthesis and strand switching are performed using kit-supplied oligonucleotides. The kit contains 24 primer pairs which are used to generate and then amplify double-stranded cDNA by PCR amplification using primers that contain 5’ tags and facilitate the ligase-free attachment of Rapid Sequencing Adapters. Amplified and barcoded samples are then pooled together and the Rapid Sequencing Adapters are added to the pooled mix.
This cDNA kit (Kit 11) includes the Rapid Adapter T (RAP T), with two key features: Firstly, the adapter is higher capture, enabling lower flow cell loading amounts. Secondly, the adapter contains the fuel fix technology, enabling users to run long experiments without the need for fuel addition during the run.
The PCR-cDNA Sequencing Kit also includes a new cDNA RT adapter and RT primer to prime cDNA synthesis from the end of a transcript to reduce overlaps during the reverse transcription step and to allow users to measure polyA tail lengths.
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.
