DNA Isolation – Ava Withering Syndrome Transmission Study Tissues

Isolated DNA from 26 red abalone digestive gland tissue samples.

Tissue was weighed, minced with a razor blade, and transferred to 2mL snap cap tube containing 1mL of InhibtEX Buffer.

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

  • Minced tissue was incubated at 70C O/N
  • Followed “human DNA analysis” protocol (to maximize sample recovery)
  • Eluted DNA with 100μL Buffer ATE

DNA Extraction – Ava Withering Syndrome Transmission Study Tissues

Isolated DNA from 19 red abalone digestive gland tissue samples.

Tissue was weighed and then DNA extracted.

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 later today.

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.

DNA Extraction – Ava Withering Syndrome Transmission Study Feces

Isolated DNA from 36 fecal samples provided by Ava. Fecal samples were on filters stored at -80C. Samples were thawed slightly to allow unrolling of the filters. Feces was transferred to pre-weighed tubes and then weighed.

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

  • Samples were 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 the boxes “Ava WS Transmission DNA Extractions by Sam Box 2″. See the master spreadsheet at the bottom of this post for specific sample locations within this box.

Samples will be quantified tomorrow.

See two pictures below for potential anomalous samples.

This sample had a date of 9/24/15. Possibly incorrect, as no other samples have this date.

 

 

This sample contained no feces at all. Additionally, the filter was a different type than all the other fecal samples. It looks like a water sample filter. Collected liquid from filter and processed that.

DNA Extraction & Quantification – Ava Withering Syndrome Transmission Study Tissues

Isolated DNA from 35 tissue samples provided by Ava. Presumably, the tissues were digestive gland and I believe they were preserved in ethanol. The list of samples are listed below.

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

After extraction, the samples were quantified using the Roberts Lab Qubit 3.0 (Life Technologies) using the Qubit ds DNA BR reagents. Used 1μL of each sample.

Samples were stored at 4C in FSH240 in the boxes “Ava WS Transmission DNA Extractions by Sam Box 2″. See the master spreadsheet at the bottom of this post for specific sample locations within this box.
