Observations

This isopod was collected near dry bushes in the morning (around 10 AM). There were a couple of its kind (around 3 others) in the surrounding area.
Putative identification Arthropoda Malacostraca Isopoda

Methods
Extraction kit Edwards Buffer
DNA extraction location Abdomen
Single or Duplex PCR Duplex Reaction
Gel electrophoresis system MiniPCR
Buffer 1X TAE
DNA stain 100X Fast Blast

DNA Stain

We used an overnight stain and let it stain for approximately 24 hours.

Gel Electrophoresis

10 microliters of sample were added per well for this 1% agarose gel.

This is the lane order for the gel:

1. DNA Ladder

2. High Altitude Roly-Poly #1 (Palos Verdes) – this isopod.

3. High Altitude Roly-Poly #2 (Palos Verdes)

4. Low Altitude Roly-Poly #3 (CSUDH)

5. Low Altitude Roly-Poly #4 (CSUDH)

6. Positive Arthropod CO1F Gene Control

7. Negative Arthropod CO1F Gene Control

8. Positive DNA Control

9. Water

Results
Wolbachia presence No
Confidence level High
Explanation of confidence level

We present high confidence as there was a distinct band present in this lane for the arthropod-specific gene and nothing for the Wolbachia.
