DNA Isolation – Olympia oyster whole body

Continued the extractions that Steven began yesterday and this morning using the E.Z.N.A. Mollusc DNA Kit (Omega Bio-Tek) after the RNase treatment @ 70C.

  • Samples were cooled to RT (~10mins)
  • Added 300μL of 100% EtOH to each (equivalent to the volume of aqueous phase Steven recovered from each sample)
  • Followed manufacturer’s protocol
  • Eluted all samples with 50μL of Elution Buffer
  • Spec’d on Roberts Lab NanoDrop1000

 

Results:

 

 

 

DNA looks absolutely pristine and has amazing yields.

Will check gDNA integrity via agarose gel tomorrow.

Data has been entered into the master spreadsheet for this project: Ostrea lurida Project Master Tissue Sample List

RAD-Seq Library Prep Reagents

A box with the above title was established in the -20C in FTR 209 containing the following:
