Nanopore-only Microbial Isolate Sequencing Solution (NO-MISS) associated extraction protocols

We have developed four optimised extraction methods to generate high quality genomic DNA from your cell cultures, allowing maximised sequencing output using the Nanopore-only Microbial Isolate Sequencing Solution (NO-MISS) - Rapid Barcoding Kit V14 (SQK-RBK114.24 or SQK-RBK114.96) end-to-end protocol.

Sample extraction method Sample type Sample Input Expected yield Expected DNA Integrity Number (DIN) Average sequencing read lengths Extraction kits used
Universal bead-beating gDNA extraction Universal applications: bacteria, fungi or yeast 1 ml liquid overnight culture (~1 x 10^8 – 10^9 cfu/ml) or half of a loop of colonies from a plate >200 ng/µl per sample 7-9 ~4-7 kb QIAGEN PowerBead Tube and Promega Maxwell® RSC PureFood Pathogen kit
Bacteria gDNA extraction Bacterial 200 µl liquid overnight culture (~1 x 10^8 – 10^9 cfu/ml) or 1/8 of a loop of colonies from a plate ~15-20 ng/µl per sample 9 >7 kb - Size will vary based on sample input species NEB Monarch Genomic DNA Purification Kit
Hard to lyse organisms gDNA extraction Mycobacterium tuberculosis
(or hard to extract bacterial samples)
5 – 10 mg cells from solid or liquid media ~15-40 ng/µl per sample 8 >7 kb - Size will vary based on sample input species NEB Monarch Genomic DNA Purification Kit
Fungi gDNA extraction Fungi or yeast 2 ml of ~1 x 10^7 cfu/ml overnight culture or a full 10 µl inoculating loop from a plate ~40 ng/µl per sample N/A >7 kb - Size will vary based on sample input species NEB Monarch Genomic DNA Purification Kit

Note: The yield, DIN and sequencing read length of extracted DNA may vary depending on sample quality and species. Please ensure you are following the correct method and using high-quality sample inputs.
