Induction of pyrimidine dimers in epidermal DNA of hairless mice by UVB: an action spectrum
Journal Article
·
· J. Invest. Dermatol.; (United States)
An action spectrum for the induction of pyrimidine dimers in the epidermis of hairless mice was determined between 288 and 307 nm. The presence of pyrimidine dimers in tritium-labeled DNA extracted from exposed SKH:hairless-1 mouse skin was determined using dimer-specific nucleases from Micrococcus luteus in conjunction with sedimentation of the irradiated DNA in alkaline sucrose gradients. The rate of induction of pyrimidine dimers was maximal at 293 nm. These values were used to propose a UVB transmission curve for mouse epidermis.
