The binding of [(3)H]3-methylcholanthrene to the DNA of hamster fibroblasts was studied by using chemical methods for DNA degradation. DNA depurinated by mild acid hydrolysis released approximately half of the radioactivity at the same rate as the purine bases, but the resulting apurinic acid still contained radioactive carcinogen.
通过使用化学方法降解DNA,研究了[(3)H] 3-甲基胆蒽与仓鼠成纤维细胞DNA的结合。经温和酸水解脱嘌呤的DNA以与嘌呤碱基相同的速率释放出约一半的放射性,但所得的脱嘌呤酸仍含有放射性致癌物。
