DNA Extraction – Ava Withering Syndrome Transmission Study Tissues

Isolated DNA from 117 tissue samples that I weighed out yesterday.

DNA was extracted using the QIAmp Fast DNA Stool Mini Kit (Qiagen) following the manufacturer’s protocol with the following options:

  • Samples were briefly homogenized (due to their stiffness resulting from ethanol fixation) in the InhibitEX Buffer using disposable plastic pestles.
  • Homogenized tissue was incubated at 95C to maximize cell lysis
  • Followed “human DNA analysis” protocol for remainder of protocol (to maximize sample recovery)
  • Eluted DNA with 100μL Buffer ATE

Samples were stored at 4C in FSH240 in racks for qPCR and quantification next week.
