Protocol notes

DNA extraction: I made sure to crush the arthropod really well dissecting the abdomen and not the exoskeleton.

Gel Electrophoresis Lanes for CO1 Arthropod:

1- 1000bp ladder

2- Arthropod positive PCR Product

3- Wolbachia negative PCR Product

10- Control DNA

Results
Wolbachia presence Yes
Confidence level High
Explanation of confidence level

All controls worked as expected. The arthropod band did appear on my gel as expected with no band appearing on the gel for Wolbachia. I had no problems with the protocol. So I am confident my arthropod is not infected with Wolbachia.
