1. Overview of the protocol
Ligation Sequencing Kit XL V14 features
This kit is recommended for users who:
- Would like to process multiple samples simultaneously, either with a multichannel pipette or a liquid-handling robot
- Would like to achieve raw read sequencing modal accuracy of Q20+ (99%) or above
- Require control over read length
- Would like to utilise upstream processes such as size selection, whole genome amplification, or enrichment for long reads
éèŠ
Optional fragmentation and size selection
By default, the protocol contains no DNA fragmentation step, however in some cases it may be advantageous to fragment your sample. For example, when working with lower amounts of input gDNA (100 ng â 500 ng), fragmentation will increase the number of DNA molecules and therefore increase throughput. Instructions are available in the DNA Fragmentation section of Extraction methods.
Additionally, we offer several options for size-selecting your DNA sample to enrich for long fragments - instructions are available in the Size Selection section of Extraction methods.

Kit 14 sequencing and duplex basecalling info sheet
The Kit 14 chemistry is a new development from Oxford Nanopore Technologies with improved duplex basecalling, which requires a different set of tools. For more information, please see the Kit 14 sequencing and duplex basecalling info sheet. We strongly recommend that you read it before proceeding with Kit 14 chemistry sequencing experiments and basecalling duplex data.
Introduction to the automated Ligation Sequencing protocol for DNA
This protocol describes how to carry out sequencing of a DNA sample using the Ligation Sequencing Kit XL (SQK-LSK114-XL).
We have developed this automated protocol on the Hamilton NGS STAR 96 liquid handling robot. The majority of the process is automated with minimal hands-on time which is required for sample quantification and deck re-loading.
It is highly recommended that a Lambda control experiment is completed first to become familiar with the technology.
To efficiently load multiple PromethION Flow Cells, we recommend using the Loading multiple PromethION Flow Cells protocol as a guideline.
Steps in the sequencing workflow:
Prepare for your experiment You will need to:
- Extract your DNA and check its length, quantity and purity. The quality checks performed during the protocol are essential in ensuring experimental success.
- Ensure you have your sequencing kit, the correct equipment, primed liquid-handling robot and third-party reagents
- Download the software for acquiring and analysing your data
- Check your flow cells to ensure they have enough pores for a good sequencing run
__Library preparation__ You will need to:
- Repair the DNA and prepare the DNA ends for adapter attachment
- Attach sequencing adapters supplied in the kit to the DNA ends
- Prime the flow cell and load your DNA library into the flow cell
Sequencing and analysis You will need to:
- Start a sequencing run using the MinKNOW software which will collect raw data from the device and convert it into basecalled reads

Input DNA
How to QC your input DNA
It is important to use a plate reader to ensure the input DNA meets the quantity and quality requirements. Using too little or too much DNA, or DNA of poor quality (e.g. highly fragmented or containing RNA or chemical contaminants) can affect your library preparation.
For instructions on how to perform quality control of your DNA sample, please read the Input DNA/RNA QC protocol.
Input file worklist
A worklist input Excel file is required prior to running the protocol on the Hamilton NGS STAR 96. These contain information regarding the appropriate number of samples and well identifiers.
Example:
Source_SampleID | Source_Well | Target_Well |
---|---|---|

Optional fragmentation and size selection
By default, the protocol contains no DNA fragmentation step, however in some cases it may be advantageous to fragment your sample. For example, when working with lower amounts of input gDNA (100 ng â 500 ng), fragmentation will increase the number of DNA molecules and therefore increase throughput. Instructions are available in the DNA Fragmentation section of Extraction methods.
Additionally, we offer several options for size-selecting your DNA sample to enrich for long fragments - instructions are available in the Size Selection section of Extraction methods.
Prepare the NEBNext FFPE DNA Repair Mix and NEBNext Ultra II End Repair / dA-tailing Module reagents in accordance with manufacturerâs instructions, and place on ice.
For optimal performance, NEB recommend the following:
Thaw all reagents on ice.
Flick and/or invert the reagent tubes to ensure they are well mixed.
Note: Do not vortex the FFPE DNA Repair Mix or Ultra II End Prep Enzyme Mix.Always spin down tubes before opening for the first time each day.
The Ultra II End Prep Buffer and FFPE DNA Repair Buffer may have a little precipitate. Allow the mixture to come to room temperature and pipette the buffer up and down several times to break up the precipitate, followed by vortexing the tube for 30 seconds to solubilise any precipitate.
Note: It is important the buffers are mixed well by vortexing.The FFPE DNA Repair Buffer may have a yellow tinge and is fine to use if yellow.
Prepare each DNA sample per well with nuclease-free water in the input plate.
- Per sample, transfer 1 ÎŒg (or 100-200 fmol) of input DNA into a well of the input plate
- Adjust the volume to 48 ÎŒl with nuclease-free water
- Mix thoroughly by pipetting
- Spin down briefly in a microfuge

We recommend loading the following amount of prepared library onto the R10.4.1 flow cell:
For high output of simplex data, load 35-50 fmol of final library. This is to ensure high pore occupancy of >95% is reached. How to calculate pore occupancy can be found here.
For duplex data, load 10-20 fmol of final library. Loading more than 20 fmol of DNA can reduce the rate of duplex read capture.
ãã³ã
Library storage recommendations
We recommend storing libraries at 4°C for short term storage or repeated use, for example, re-loading flow cells between washes. For single use and long term storage of more than 3 months, we recommend storing libraries at -80°C. For further information, please refer to the Library Stability Know-How document.
ãªãã·ã§ãã«ã¹ããã
If quantities allow, the library may be diluted in Elution Buffer (EB) for splitting across multiple flow cells.
Depending on how many flow cells the library will be split across, more Elution Buffer (EB) than what is supplied in the kit will be required.

This kit is only compatible with R10.4.1 flow cells (FLO-PRO114M).
Using the Library Solution
For most sequencing experiments, use the Library Beads (LIB) for loading your library onto the flow cell. However, for viscous libraries it may be difficult to load with the beads and may be appropriate to load using the Library Solution (LIS).

Pore occupancy below 40%
Observation | Possible cause | Comments and actions |
---|---|---|
Pore occupancy <40% | Not enough library was loaded on the flow cell | Ensure you load the recommended amount of good quality library in the relevant library prep protocol onto your flow cell. Please quantify the library before loading and calculate mols using tools like the Promega Biomath Calculator, choosing "dsDNA: µg to pmol" |
Pore occupancy close to 0 | The Ligation Sequencing Kit was used, and sequencing adapters did not ligate to the DNA | Make sure to use the NEBNext Quick Ligation Module (E6056) and Oxford Nanopore Technologies Ligation Buffer (LNB, provided in the sequencing kit) at the sequencing adapter ligation step, and use the correct amount of each reagent. A Lambda control library can be prepared to test the integrity of the third-party reagents. |
Pore occupancy close to 0 | The Ligation Sequencing Kit was used, and ethanol was used instead of LFB or SFB at the wash step after sequencing adapter ligation | Ethanol can denature the motor protein on the sequencing adapters. Make sure the LFB or SFB buffer was used after ligation of sequencing adapters. |
Pore occupancy close to 0 | No tether on the flow cell | Tethers are adding during flow cell priming (FLT/FCT tube). Make sure FLT/FCT was added to FB/FCF before priming. |

Reduction in sequencing speed and q-score later into the run
Observation | Possible cause | Comments and actions |
---|---|---|
Reduction in sequencing speed and q-score later into the run | For Kit 9 chemistry (e.g. SQK-LSK109), fast fuel consumption is typically seen when the flow cell is overloaded with library (please see the appropriate protocol for your DNA library to see the recommendation). | Add more fuel to the flow cell by following the instructions in the MinKNOW protocol. In future experiments, load lower amounts of library to the flow cell. |

Guppy â no input .fast5 was found or basecalled
Observation | Possible cause | Comments and actions |
---|---|---|
No input .fast5 was found or basecalled | input_path did not point to the .fast5 file location | The --input_path has to be followed by the full file path to the .fast5 files to be basecalled, and the location has to be accessible either locally or remotely through SSH. |
No input .fast5 was found or basecalled | The .fast5 files were in a subfolder at the input_path location | To allow Guppy to look into subfolders, add the --recursive flag to the command |
Guppy â no Pass or Fail folders were generated after basecalling
Observation | Possible cause | Comments and actions |
---|---|---|
No Pass or Fail folders were generated after basecalling | The --qscore_filtering flag was not included in the command | The --qscore_filtering flag enables filtering of reads into Pass and Fail folders inside the output folder, based on their strand q-score. When performing live basecalling in MinKNOW, a q-score of 7 (corresponding to a basecall accuracy of ~80%) is used to separate reads into Pass and Fail folders. |
Guppy â unusually slow processing on a GPU computer
Observation | Possible cause | Comments and actions |
---|---|---|
Unusually slow processing on a GPU computer | The --device flag wasn't included in the command | The --device flag specifies a GPU device to use for accelerate basecalling. If not included in the command, GPU will not be used. GPUs are counted from zero. An example is --device cuda:0 cuda:1, when 2 GPUs are specified to use by the Guppy command. |
