Information

This kit is recommended for users who:

  • want to optimise their sequencing experiment for throughput
  • require control over read length
  • would like to utilise upstream processes such as size selection or whole genome amplification.

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 Ligation Sequencing Kit offers a flexible method of preparing sequencing libraries from dsDNA (e.g. gDNA, cDNA or amplicons). The library preparation method is straightforward: DNA ends are repaired and dA-tailed using the NEBNext End Repair/dA-tailing module, and then sequencing adapters, supplied in the kit, are ligated onto the prepared ends.

The kit is optimised to generate maximum throughput and read length. For highest data yields, we recommend starting with 50-100 fmol of pure input DNA. Starting with lower amounts of input material, or impure samples, can affect library preparation efficiency and can reduce sequencing throughput.

The kit contains an updated sequencing adapter (Adapter Mix F, or AMX-F), which is designed to turn over significantly less fuel during a sequencing run compared to previous kit versions. This results in better maintenance of enzyme speed and higher sequencing output.

Kit9 vs Kit10 translocation2

Users can either start with 1 μg of gDNA, quantified using the Qubit fluorometer, or 50 fmol of shorter-fragment input such as amplicons or cDNA. If your experiment requires long reads, it is recommended to start with full-length gDNA, and fragmentation/shearing is neither advised nor required. Please note: if long reads are required, then long fragments must be present in the starting material. To determine purity, we suggest using the Nanodrop to measure the A260/280 and A260/230 ratios and we recommend that the sample should meet the following criteria:

  • A260/280 = 1.8
  • A260/230 = 2.0-2.2

The Ligation Sequencing Kit is compatible with upstream processes such as target enrichment by sequence capture, whole genome amplification (for applications where under 1 ng of sample is available) and size selection (for enrichment of specified fragment lengths, using the BluePippin, for example). When size selecting, we recommend increasing the amount of input used, as size selection can be a wasteful process.

Ligation fragmentation comparison

The relative sequencing yields (A) and typical read-length histograms (B, C and D) observed when preparing E.coli libraries using the Ligation Sequencing Kit without or with g-TUBE fragmentation or with size selection (without fragmentation).

PCR- and WGA-free workflows remove amplification bias and retain base modification information, which can be analysed using tools developed in the Nanopore Community.

Further considerations:

Starting with lower amounts of input material, or impure samples, can affect library preparation efficiency and can reduce sequencing throughput. PCR can be used to generate more input material in cases where sample amount is limiting. Also, where sample purity is compromised and library preparation efficiency may be reduced, PCR will select for molecules which have been successfully adapted, and generate more of them. The original impurity is lost or diluted. It is often observed that a sample which produces poor sequencing results can be improved by inclusion of PCR. However, if PCR is likely to be the main method of library preparation, we recommend the PCR Sequencing Kit, or Rapid PCR Sequencing Kit.
While any dsDNA can be used as a template for the Ligation Sequencing Kit, users planning to regularly sequence amplicons or cDNA, should consider specific kits with dedicated protocols which simplify the laboratory workflow and produce superior results. For amplicons, we recommend using our four-primer PCR protocol along with the PCR Sequencing Kit (or PCR Barcoding Kit for multiplexing amplicons), and for cDNA we recommend the PCR-cDNA Sequencing Kit or the Direct cDNA Sequencing Kit.

Shipping and logistics:

Workflow

The Ligation Sequencing Kit offers a flexible method of preparing sequencing libraries from dsDNA (e.g. gDNA, cDNA or amplicons). The library preparation method is straightforward: DNA ends are FFPE repaired and end-prepped/dA-tailed using the NEBNext End Repair/dA-tailing module, and then sequencing adapters, supplied in the kit, are ligated onto the prepared ends.
