Profiles of protein expression by Listeria monocytogenes at different doses of γ-irradiation treatment.

aThe values of corrected area presented are the mean ± standard deviation of samples prepared in duplicate and each injected three times. 0 kGy, control without radiation treatment, 1.2 kGy, damaged cells; 3.5 kGy, lethal. ND is not-determined.*Corrected area differs statistically from the non-irradiated protein by Student's t test with p≤0.05.
