Information
This kit is recommended for users who:
- Want to optimise their sequencing experiment for output
- Wish to low-plex samples for Whole Genome Sequencing (WGS)
- Need a PCR-free method of multiplexing to preserve additional information, such as base modifications
- Require control over read length
- Would like to utilise upstream processes, such as size selection or whole genome amplification
- Would like to process multiple samples simultaneously, either with a multichannel pipette
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 Multiplex Ligation Sequencing Kit XL V14 is a standalone kit providing 96 unique barcodes to enable PCR-free multiplexing of dsDNA samples such as gDNA and amplicons. This kit provides an easier workflow to enable Whole Genome Sequencing (WGS) by enabling low-plex sequencing, allowing users to identify regions more common and others more prone to mutations.
This kit has been upgraded to use our Kit 14 chemistry, which includes improved modal raw read sequencing accuracies (Q20+) with high output on our latest nanopore: R10.4.1. The flow cell priming and sequencing reagents included as part of the sequencing kit have been reformulated to be compatible with the Kit 14 chemistry upgrade and R10.4.1 nanopore. Other upgrades include higher capture rate of gDNA 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.
The library preparation is similar to the Ligation Sequencing Kit protocol; DNA ends are repaired and dA-tailed using the NEBNext End Repair/dA-tailing module, and then a unique dT-tailed barcode adapter is ligated on the dA-tailed template. Barcoded samples are then pooled together. Each barcode adapter also has a cohesive end and this is used as a hook to ligate to the supplied sequencing adapters.
We recommend starting with 1 ug gDNA per sample and our manual protocol recommends sequencing two samples per flow cell to sequence up to 96 samples across 48 flow cells. Three samples across two flow cells can also be used to sequence up to 96 samples across 64 flow cells to maximise data output.
Deconvolution of barcoded sequencing data is supported by the MinKNOW software, the stand-alone Guppy basecaller, and EPI2ME Labs, all of which classify the barcode sequence and sort reads into corresponding folders.
