Protocol notes

10-fold dilutions (20µl 18µl of distilled water, 2µl of original sample) were performed on template PCR due to the original DNA concentrations of the sample being too high, causing no reading on the gel. The gel submitted is the gel taken of the diluted samples, the second gel overall.


Wolbachia presence Unknown
Confidence level High
Explanation of confidence level

The Wolbachia portion of the gel didn’t yield any results, including the controls(the only aspect visualized on the gel was the loading buffer). The only conclusive results were sample 2 in lane 2 of the arthropod portion of the gel, as a band is clearly pictured at around 700 bp(base pairs) on the gel. In addition, the arthropod controls yielded results at around 700 bp.
