Spider was caught on my bathroom wall. it was caught mid-June; the outside temperatures were in the 80’s, the inside temperature was mid-60’s.

Putative identification Arthropoda Chelicerata Arachnida Araneae

DNA extraction location Abdomen
Single or Duplex PCR Single Reaction
Gel electrophoresis system MiniOne
Buffer TBE

Protocol notes

The only thing I would redo for our lab would be the injection of the DNA/Controls into the gel. During this process we would occasionally go to deep or puncture the gel.


Wolbachia presence No
Confidence level High
Explanation of confidence level

When we completed the PCR test, there weren’t any lines in an unexpected value, therefore there was no detected contamination in our tests. Our positive controls worked, and our negative controls showed no signs of contamination. The DNA ladder is a little weak, so we think we punctured the gel when prepping for Gel electrophoresis.
