Sample requirements
General sample submission criteria
- Samples should be intact i.e. not degraded.
- Samples should be free of contaminants: 260:280 1.8-2.2 and 260:230 ratio >1.8.
- RNA samples must be free of genomic DNA contamination.
- DNA samples must be free of RNA contamination.
- DNA concentration should be measured using the Qubit or Picogreen assay as quantification by spectrophotometric methods is inaccurate.

- >300ng of purified plasmid DNA at a concentration of 15-50ng/ul (measured with Qubit) in nuclease free water or elution buffer.
- Minimum volume 20ul/sample.
- Plasmid size: 2-25kb. Please contact us if the plasmid is outside this size range as this may affect quantity of DNA required.
- 260/280: 1.8 - 2.0
- DNA is double-stranded and not fragmented (degraded).
- The sample does not contain a mixture of plasmids.
- The DNA is clean and does not contain contaminants that may affect prep or sequencing results.
For more information, see the Oxford Nanopore guideline for plasmid extraction.
Please note, submitted samples are only checked with qubit. By submitting, the client confirms that the samples conform to the above requirements.

Axiom Genotyping:
50ul of intact genomic DNA at a concentration of 15 - 50 ng/ul.
Infinium Genotyping:
20ul of intact genomic DNA at a concentration of 40 - 60 ng/ul.
Infinium Methylation array:
