Abstract The DNA double-strand break DSB is the primary lethal lesion after therapeutic radiation. Thus the development of assays to detect and to quantitate these lesions could have broad preclinical and clinical impact. Phosphorylation of histone H2AX to form Y-H2AX is a known marker for irradiation-induced DNA DSBs. However the first generation assay involves the use of immunofluorescent staining of Y-H2AX foci. This assay is time consuming operator dependent and is not scalable for high throughput assay development. Thus we sought to develop a new assay using a high throughput electrochemiluminescent platform from Mesoscale Discovery Systems to quantify Y-H2AX levels. The results show that our assay utilizes significantly less time and labor has greater intra-assay reproducibility and has a greater dynamic range of Y-H2AX versus .
