I have used low dose, UVC irradiation to induce cellular changes in addition to DNA damage. You should be careful in choosing your dose. If you want primarily damage DNA, UVC is the best as it is closest to the absorption spectra of nucleic acids. PMID: 19003995
Thanks for the reply , I have few questions regarding Damage induction, if you could send me your email, i would be really happy to write you in detail.
I am using Uvitec CL-508.G UV cross linker which emits UV light at 254 nm wavelength (UV C). So how much UV and time needed to Introduce Double stranded breaks. I am suppose to monitor DNA damage makers in the cells by WB and RT PCR.
