Protocol notes

Lane 1: 100Kb Ladder

Lane 2: Negative control

Lane 3: Positive Control

Lane 4: Other arthropod tested (Wasp)

Lane 5: Beetle tested

Lane 6: Water

Two arthropods were tested and are shown on the gel. DNA for the beetle, Coleoptera Geotrupidae is shown on lane 5. 6x loading dye was used for our samples, and ran at 100 V for 30 minutes.



Wolbachia presence No
Confidence level High
Explanation of confidence level

I have a very high confidence level due to the amplified band showing negative results for Wolbachia. The negative control presented with a single band on the gel and the same result appeared for the tested arthropod. The controls were amplified on the gel, negative control shows one band and positive control shows two bands.
