Figure 7. No DNA breaks are detected in induced cell death.

IPTG-induced and uninduced spirochetes were labeled with the terminal deoxynucleotidyltransferase dUTP nick end labeling assay. Labeled cells were examined and imaged under the Olympus IX71 Microscope with 535 and 480 nm wavelengths, respectively. The positive control cells provided in the labeling kit were presented in the top panel.
