In mammalian cells, a double-strand break (DSB) in genomic DNA is potentially lethal to a cell, and one of the responses to DSB formation as part of the repair process is phosphorylation of histone H2AX.

The HCS DNA Damage Kit

DNA damage can be measured as an indicator of genotoxicity using an antibody against phosphorylated H2AX. By combining specific antibody-based detection of DNA damage with a cytotoxicity indicator, both parameters can be measured simultaneously in the same cell.

The HCS DNA Damage Kit uses a secondary antibody conjugate to detect phosphorylated H2AX, Image-iT™ DEAD Green™ dye to detect cytotoxicity, and Hoechst™ 33342 to label nuclei in both live and dead cells. The kit is compatible with additional multiplexing steps, and results can be analyzed using automated image analysis techniques.
