The alkaline/filter DNA elution technique measures single-strand DNA breaks in mammalian cells based on the DNA molecular weight dependent retention of the macromolecule on 2-μm-pore-size filters. Described here is a modification of the technique which uses [3H]thymidine-labeled DNA of γ-irradiated cells as an internal reference. Thus, an increased precision is obtained in the assessment of this type of DNA damage at biologically significant radiation doses (i.e., where cell survival occurs). The measure of DNA damage is based on the actual initial DNA elution rate, i.e., arithmetic ratio of the elution of “test” DNA (i.e.,14C-labeled DNA) relative to the elution of “reference” DNA (i.e.,3H-labeled DNA). The repair of this damage on postirradiation incubation of the cells is detected as a decrease in the rate of “test” DNA cluted relative to “reference” DNA from unincubated cells. For Chinese hamster V79–171 cells irradiated with 5 Gy (500 rads), repair can be resolved into two first-order processes having rate constants (at 24°C) of ∼0.190 and ∼0.017 min−1.
