DNA was treated with DMS or MMS in 100 mM sodium cacodylate, pH 7.0, for 30 min at 30 °C, followed by ethanol precipitation of the DNA, and resuspension in 10 mM Tris, pH 8. M13 DNA in vitro ...

The proteins and chromosomal DNA after the mixing of solution III form white precipitates, which are removed by passing continuously through T5 onto the filter N comprising four sequential nylon ...

Results: The DNA damage of AGS cell depended upon ethanol concentration distinctly. Damaged cells showed up recovered tendency in the group treated with low dose RN or OP. In addition, DNA repair ...
