Induction and quantification of gamma-H2AX foci following low and high LET-irradiation.

Journal article

PURPOSE: To investigate quantitatively the induction and rejoining of DNA double strand breaks (DSB) in V79-4 and xrs-5 Chinese hamster cells and HF19 human fibroblast cells, using the phosphorylation of the histone protein H2AX (gamma-H2AX) as an indicator of DSB, exposed to low doses of either low linear energy transfer (LET) (60)Co gamma-rays or high LET a-particles. MATERIALS AND METHODS: Cells were irradiated with low or high LET (20 - 2000 mGy). The gamma-H2AX foci were detected using i...
