Sam’s Notebook:Library Construction – Geoduck Water Filter Metagenome with Nextera DNA Flex Kit (Illumina)

0000-0002-2747-368X

Made Illumina libraries with goeduck metagenome water filter DNA I previously isolated on:

We used a free Nextera DNA Flex Kit (Illumina) that we won in a contest held by Illumina!

Followed the manufacturer’s protocol for input DNA quantities <10ng with the following changes/notes:

  • PCR steps performed in 200uL thin-walled PCR tubes.
  • Magnetic separations were performed in 1.7mL snap cap tubes.
  • Thermalcycler: PTC-200 (MJ Research)
  • Magnet: DynaMag 2 (Invitrogen)

See the Library Calcs sheet (link below) for original sample names and subsequent library sample names.

IMPORTANT!

The sheet also contains the indexes used for each library. This info will be necessary for sequencing facility.

After library construction was completed, individual libraries were quantified on the Roberts Lab Qubit 3.0 (Invitrogen) with the Qubit 1x dsDNA HS Assay Kit.

2uL of each sample was used for each assay.

Library quality was assessed using the Seeb Lab 2100 Bioanalyzer (Agilent) with a High Sensitivity DNA Kit, using 1uL of each sample.

Libraries were stored in the small -20C in FTR213:
