DNA Extraction

DNA was extracted withZymo Research Quick-DNA™ 96 Kit D3010

Used Page 10 Proteinase K Digestion with DNA/RNA Shield

Used Eppendorf Deepwell Plate 96/2000 µL plates Catalog No. 951033502 for reagent and sample mixing prior to adding to Zymo column plate

The samples were extracted according to the manufacturer’s instructions for the Quick DNA 96 Kit for samples stored in DNA/RNA Shield including the addition of Proteinase K (20mg ml-1).

Added 100µl of sample + 10µl of PK Digestion Buffer + 5µl of ProteinaseK. Pipetted to mix and incubated for 5 min at room temp.

  • 4 volumes of Zymo Kit Genomic Lysis Buffer was added for each volume of the sample digestion (e.g., add 400µl of Genomic Lysis Buffer to 100µl of sample digestion). Samples were mixed via pipetting and the mixtures were incubated for 5 minutes at room temperature. Then samples were moved to the silicon-A plate columns. I added 400µl and then 5 minute spin at 2500 rcf.

  • Next 200µl of DNA Pre-wash buffer was added to each well and then the silicon-A plate was spun for 5 minute at 2500 rcf

    • used sterile 25 or 50ml plastic troughs and multi-channel pipettes
    • 192 samples x 200µl = 38.4ml - The waste was removed from the collection plate after the first centrifugation step.
  • Next 300µl of g-DNA wash buffer was added to each well and then the silicon-Aplate was spun for 5 minute at 2500 rcf - used sterile 25 or 50ml plastic troughs and multi-channel pipettes
    • 192 samples x 300µl = 57.6ml - waste was kept in the collection plate
  • The silicon-A plate was moved from the collection plate to the elution plate.

  • DNA was then eluted in 50µl of kit Elution Buffer warmed to 70°C after standing on the column for 3-5 minutes. - used sterile 25 or 50ml plastic troughs and multi-channel pipettes
    • 192 samples x 50µl = 9.6ml

Quantification of gDNA

Used Lane lab nanodrop and kit elution buffer as blank to quantify the DNA. Used 1.5µl of sample

All tested samples had DNA and can move forward for PCR.

gDNA was stored at -20°C in the elution plate covered with a foil seal.
