METHODS AND KITS FOR MEASURING AND QUANTIFYING DNA DOUBLE-STRANDED BREAKS USING GAMMA-H2AX AND H2AX

摘要

Disclosed are methods of measuring the amount of exposure of a host to a DNA double-stranded break (DSB)-causing agent by determining the ratio of the quantity of γ-H2AX to the quantity of total H2AX in a biological sample from the host as compared to the ratio of the quantity of γ-H2AX to the quantity of total H2AX in a positive control biological sample that has been exposed to a known amount of a DSB-causing agent. Related kits and methods of quantifying DSBs in a test biological sample are also disclosed.
