Protocol notes

Only one sample arthropod was collected. We used 6X loading dye for the gel electrophoresis. The gel was run at 100V until the smallest visible fragment was about two thirds down the gel.

Lane 1 is the 100 bp DNA ladder, Lane 2 is arthropod sample 1, Lane 3 is positive arthropod control, Lane 4 is negative arthropod control, Lane 5 is positive DNA control, and Lane 6 is the water blank.


Wolbachia presence No
Confidence level High
Explanation of confidence level

The positive arthropod control was amplified correctly and the 16s rRNA gene was visible on the gel and calculated to be 681 base pairs. The negative arthropod control CO1 gene was also visible on the gel at 395 base pairs. We also had a positive Wolbachia DNA control which was amplified properly and is 681 base pairs in length. The sample arthropod fragment matched the negative arthropod control fragment with a length of 681 base pairs.
