Hydrolysates of DNA that had been isolated from mouse skin treated with 3H-labelled 7,12-dimethylbenz[a]anthracene (DMBA) were subjected to chromatography on Sephadex LH20 columns and 3H-labelled products that eluted in the region expected for nucleoside-hydrocarbon adducts were purified further by high pressure liquid chromatography (h.p.l.c.). The(More)
Hydrolysates of DNA that had been isolated from mouse skin treated with 3H-labelled 3-methylcholanthrene were subjected to chromatography on Sephadex LH20 columns and 3H-labelled products that eluted in the region expected for nucleoside-hydrocarbon adducts were purified further by high pressure liquid chromatography; eight major and one minor products were(More)
The fluorescence spectral properties of the principal hydrocarbon-nucleoside adducts present in hydrolysates of DNA that had been isolated from hamster embryo cells or from mouse skin treated with benz(a)anthracene have been examined using photon-counting spectrophotofluorimetry and compared with the spectral properties of the products formed when different(More)
Hydrolysates of DNA that had been isolated from mouse skin treated with 3H-labelled benzo[a]pyrene were subjected to chromatography on Sephadex LH20. Two major products were eluted in the region expected for deoxyribonucleoside-hydrocarbon adducts and these were purified further by h.p.l.c. The fluorescence emission and excitation spectra of one of the(More)
