We describe a method for the quantitative, real-time measurement of DNA glycosylase and AP endonuclease activities in cell nuclear lysates. The assay yields rates of DNA Repair activity amenable to kinetic analysis and is adaptable for quantification of DNA Repair activity in tissue and tumor lysates or with purified proteins.
In this article, a detailed protocol for quantifying telomere length using a modified terminal restriction fragment analysis is discussed that provides fast and efficient direct measurement of telomere length. This technique can be applied to a variety of cell sources of DNA for quantifying telomere length.
Here we present a protocol to induce radiation-induced skin fibrosis in the hind limb of mice and perform post-irradiation measurements of chronic impairment via limb excursion and gait index analyses to evaluate the functional outcome. The model elucidates radiation-related skin fibrosis mechanisms and is useful in subclinical therapeutic studies.
