DNA Isolation & Quantification – Pinto Abalone

Isolated DNA from the following pinto abalone (Haliotis kamtschatkana) digestive gland tissues (stored in ethanol), collected by Sean Bennett as part of his Capstone project:

Accession Weight(mg)
15:30-01   194
15:30-04   67
15:31-01   34
15:31-02   107
15:31-03   83
15:31-04   80

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

Used the Roberts Lab Qubit 3.0 and the Qubit hsDNA Kit (high sensitivity). Used 1uL of template for all samples.

Samples were stored at -20C in FSH240 in the “Pinto Transcriptome DNA” box.

Results:

All samples have DNA.

DNA Quantification – Ava’s RLO Trasmission Samples

Quantified DNA extractions from Ava’s samples that I isolated earlier this month, as well as some older samples that I hadn’t quantified yet.

Used the Roberts Lab Qubit 3.0 and the Qubit dsDNA BR Kit (broad range). Used 5uL of template for the first and third groups and 1uL of template for the second group (see Results below).

All data was added to the master extraction spreadsheet (Google Sheet): ava_abalone_master_extraction_list

There were 65 samples with concentrations that were too high for the high sensitivity assay. Will re-quantify this samples using the broad range assay.

DNA Quantification – Ava’s RLO Transmission DNA

Quantified the DNA I isolated on 20170504 and earlier today using the Roberts Lab’s Qubit 3.0 and the dsDNA Broad Range assay.

Used 1uL of each sample.

Results:

The following samples were below the level of sensitivity of the Qubit assay:

  • 15:09-142
  • 15:11-113
  • 15:11-147
  • 15:11-149

DNA Quantification – RLO viability DNased RNA

I previously DNased RNA I isolated from water filters that were part of the RLO viability experiment that Lisa and the Capstone students are conducting. I checked for residual gDNA carryover via qPCR and all of the samples that were intended for dosing the abalone came up positive. It’s likely due to such a high quantity of algae that was co-filtered with the potential RLOs, leading to over-saturation of the RNAzol with DNA, resulting in the gDNA carryover.

In turn, I think the DNase treatment was insufficient for the quantity of carryover DNA.

I am planning on re-DNasing those samples, but want to quantify any residual DNA present to make sure that the samples aren’t still too concentrated for the DNase.

Samples were quantified using the Robert Lab Qubit 3.0 and the Qubit dsHS reagents (high sensitivity), using 1uL of sample.

Results:

Residual DNA is still present, but at levels that are well below the maximum that the DNase treatment (10ug) can handle. I will redo the DNase treatment on these samples. Spreadsheet is linked, and embedded below, with sample concentrations.

DNA Quantification – Black Abalone DNA (Black Ab Exp. 2)

Lisa recently isolated DNA from the following samples:

08:13-05 (Black Ab exp 2)
08:13-18 (Black Ab exp 2)
08:13-24 (Black Ab exp 2)
08:13-25 (Black Ab exp 2)

I quantified the samples using the Roberts Lab Qubit 3.0 with the Qubit ds High Sensitivity kit. Used 1uL of each sample.

Samples were stored in designated boxes in -20C in Rm. 240.

DNA Extraction & Quantification – Ava Withering Syndrome Transmission Study Tissues

Isolated DNA from 27 tissue samples provided by Ava. Presumably, the tissues were digestive gland and I believe they were preserved in ethanol. The list of samples can be seen in the results 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 box “Ava WS Transmission DNA Extractions by Sam Box 1″. See the master spreadsheet at the bottom of this post for specific sample locations within this box.
