Genomic DNA Isolation – Geoduck Adductor Muscle & Foot

Isolated gDNA from Panopea generosa (geoduck) adductor muscle & foot samples collected by Brent & Steven on 20150811 using the E.Z.N.A Mollusc DNA Kit (Omega Bio-Tek) according to the manufacturer’s protocol, with the following adjustments:

  • 41.8mg of adductor muscle
  • 30.0mg of foot used
  • Tissues homogenized in 350μL of ML1 Buffer with disposable mortar/pestle tubes using only three pestles strokes
  • Homogenized tissue incubated in ML1 Buffer + Proteinase K @ 60C for 2.5hrs
  • Added 265μL of MBL Buffer
  • Added 514μL of 100% EtOH.
  • Eluted with 75μL Elution Buffer.

Spec’d on Roberts Lab NanoDrop1000 (ThermoFisher) and stored temporarily at 4C to avoid freeze-thawing before sending off for sequencing next week.






Yields are good (~7ug).

Quality (260/280 ratios) looks great for both samples.

260/230 ratio not very good for adductor muscle, but perfect for foot tissue.

Will run samples on gel to assess gDNA integrity.
