After DNA is damaged, DNA-repair synthesis would occur. This function is closely related with the alteration of cancer-cell, heritable disease, etc. Measurement of DNA-repair synthesis function is an important method in the study of the above diseases of molecular level and in the risk assessment for chemical mutagens.

In 1972 Koide et al. first used the 210Pb technique and a good result was obtained. Thereafter,展开更多
