title: The crypto-OH radical in the damage of DNA by bleomycin-Fe2+?
abstract: 1. Effects of various OH scavengers, superoxide dismutase and catalase on the formation of malondialdehyde-like products from DNA by bleomycin-Fe2+ were studied. In no case was a protective effect observed. 2. These results can be interpreted on the basis that a crypto-OH radical mediates the damage to DNA by bleomycin-Fe2+.
