Protocol notes

10kb DNA ladder used.

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. 10kb DNA ladder used.


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.

Wolbachia 16S sequence
Arthropod COI sequence
Summary The Xyloryctes jamaicensis was found to be negative for Wolbachia.
