This kit is recommended for users who:

• want to do 16S sequencing
• are interested in genus-level bacterial identification

Barcoding or multiplexing is useful when the amount of data required per sample is less than the total amount of data that can be generated from a single flow cell: it allows a user to pool multiple samples and sequence them together, making more efficient use of the flow cell.

Multiplexing samples onto one flow cell can reduce the cost per sample for a user. Below are some worked examples:

The 16S Barcoding Kit offers a method of amplifying the entire ~1,500 bp 16S rRNA gene from extracted gDNA, followed by library preparation. By narrowing down to a specific region of interest, a user can see all the organisms in the sample without sequencing unnecessary regions of the genome, making the identification quicker and more economical. On the other hand, analysing the full 16s rRNA gene is more informative than analysing a subset of exons.

The 16S Barcoding Kit features:

The DNA is amplified by PCR using specific 16S primers (27F and 1492R) that contain 5’ tags which facilitate the ligase-free attachment of Rapid Sequencing Adapters.

The kit is supported by the EPI2ME FASTQ 16S workflow, which can be used to analyse data from the 16S protocol. Deconvolution of barcoded sequencing data is supported by Guppy and EPI2ME which classify the barcode sequence and sort reads into corresponding folders.

Further considerations:

Oxford Nanopore Technologies deem the useful life of the product to be 3 months from receipt by the customer.

The DNA is amplified by PCR using specific 16S primers (27F and 1492R) that contain 5’ tags which facilitate the ligase-free attachment of Rapid Sequencing Adapters. The kit contains 24x barcoded primer pairs.

The kit is supported by the EPI2ME 16S-BLAST workflow, which can be used to analyse data from the 16S protocol. Deconvolution of barcoded sequencing data is supported by Guppy and EPI2ME, which classify the barcode sequence and sort reads into corresponding folders.
