The scorpions were stored in a freezer for about 2 weeks until extraction.

DNA Extraction: The DNA was extracted from the abdomen. All of the Dneasy (Qiagen) protocols were followed. The extraction took one day to complete.

Wolbachia presence Yes
Confidence level High
Explanation of confidence level

I am confident Lane 3, 4, and 5 are positive because they are double banded. There was something wrong with Lane 2 which may be due to an error in DNA extraction.
