RAD51 immuno-positive signals. DAPI column shows DAPI nuclear staining (blue); Rad51 column shows the same DAPI-stained cells expressing Rad51 protein (green). Ozone treatment was able to increase Rad51 immuno-profiles (red arrows). CTR + O2 = oxygen-treated rats; CTR + O3 = ozone-treated rats; STZ + O2 = oxygen-treated STZ rats; STZ + O3 = ozone-treated STZ rats. Negative CTR: Negative control (without primary antibody) for staining in order to confirm antibody specificity.
