The BioMicro Center utilizes the SQK-LSK114 kit for most dsDNA library preparation. This kit requires 1 ug of dsDNA and can accommodate a variety of fragment sizes. The enzymes are purchased directly from New England Biolabs or Kapa/Roche. DNA fragments are repaired, A-tailed and ligated to adapters. The ligated products are size-selected using SPRI beads. Prepared libraries can be quantified by Qubit prior to loading.

The BioMicro Center utilizes the SQK-NBD14 kit for dsDNA library preparation that wants barcoding. This kit requires 1 ug of dsDNA and can accommodate a variety of fragment sizes. The enzymes are purchased directly from New England Biolabs. DNA fragments are repaired, A-tailed, barcoded with ONT barcodes, and ligated to adapters. The ligated products are size-selected using SPRI beads. The libraries are pooled and run on a single flow cell. Prepared libraries can be quantified by Qubit prior to loading.

The BioMicro Center utilizes the SQK-RBK114 kit for tagmentation-based library preparation for dsDNA of large size distributions. Oxford recommends sizes greater than 30 kbp with input of at least 400 ng. The enzymes are bought directly from New England Biolabs. Input is tagmented with adapters and the products are size selected using SPRI beads. Prepared library will be quantified by Qubit prior to loading.
This kit can also be used when users are interested in obtaining the longest reads possible. For this protocol, micrograms of clean genomic DNA must be used. No size selection is performed. The PromethION P24 has sequenced reads with lengths of 300 kbp+: however, these long reads are rare outliers and the overall read amount for the flowcell in use will be lowered. Longer DNA and/or carryover seems to kill the nanopores faster and requires a large amount of computing power from the sequencer, reducing the amount of flowcells that can be simultaneously loaded on the sequencer.

The BioMicro Center utilizes the SQK-RNA002 kit for library preparation with RNA. The enzymes are purchased directly from New England Biolabs. The typical workflow uses first strand synthesis to create a site for ligation--this step can be omitted if necessary, but significantly reduces read amount. Input is ligated with adapters and the products are size selected using SPRI beads. Prepared library can be quantified by Qubit prior to loading.
SPRI bead cleans, poly-T bead selection, gel separation and other methods can be added to further select the population of RNA prior to library preparation and sequencing.
