Description

Measured by gel electrophoresis scanning, it was shown that the double-strand breaks (DSBs) of pBR322 irradiated by γ-rays were constituted by two parts, αDSB and βDSB and the relationship between α, β and scavenging capacity σ was obtained. Results showed that β/α non-linearly decreased with increasing σ. Moreover, the yield of the OH free radicals reacting with DNA was analyzed
