Methods

Extraction kit DNeasy (Qiagen)
DNA extraction location Whole arthropod
Single or Duplex PCR Single Reaction
Gel electrophoresis system MiniPCR
Buffer TBE
DNA stain GelGreen
Gel images
Protocol notes

The controls for Wolbachia were successful when the gel was run, but there was no visible band. The sample was not sent for sequencing.

Results

Wolbachia presence Unknown
Confidence level Low
Explanation of confidence level

We did not get good results in the arthropod gel, indicating that we messed up somewhere else in the process because the specimen should have been positive for the arthropod gene
