The Ultra-Long DNA Sequencing Kit V14 offers a means of preparing ultra-high molecular weight (uHMW) DNA for sequencing, which has shown to give N50s >50 kb and reads up to 4+ Mb. The kit is based on transposase chemistry: the transposase simultaneously cleaves template molecules and attaches tags to the cleaved ends. Rapid sequencing adapters are then added to the tagged ends. The last step is an overnight elution of the DNA library.
This kit has been updated to use our newest Kit 14 chemistry which includes improved modal raw read sequencing accuracies with higher output on our latest nanopore: R10.4.1. Our flow cell priming and sequencing reagents have been reformulated to be compatible with the Kit 14 chemistry upgrade and R10.4.1 nanopore.
Kit 14 also includes previous updates such as higher capture rate of DNA to enable lower flow cell loading amounts, and fuel fix technology, allowing users to run longer experiments without the need for fuel addition during the run.
Specific to the Ultra-Long Sequencing Kit V14, we now supply the Extraction EB (EEB) and Precipitation Buffer (PTB) prepared for customer use and updated the Flush Tether UL (FTU) for Kit 14 compatibility. A Precipitation Star (PS) is also provided in this kit to aid DNA precipitation and recovery.
For an end-to-end workflow, we have used the NEB Monarch® HMW DNA Extraction Kit for Tissue to extract uHMW gDNA, enabling users to extract and sequence their sample in just one day.
Validated inputs for the end-to-end protocol are:
- 6 million human cells isolated from culture (e.g. GM24385)
- 6 million peripheral blood mononuclear cells (PBMCs) from blood
These inputs produce high read N50s and, when paired with the Flow Cell Wash Kit (EXP-WSH004), deliver high outputs on both MinION and PromethION.
