The unique methionine residue of bovine alpha-lactalbumin was modified by irreversible alkylation with the bromoacetamido nitroxide spin-label 4-(2-bromoacetamido)-2,2,6,6-tetramethylpiperidine-N-oxyl. The line shape of the electron spin resonance (ESR) spectrum was indicative of a fairly mobile spin-label and was sensitive to the

1. Incubation with hydralazine was shown to induce degradative changes of calf thymus DNA spin-labeled with 3-(2-bromoacetamido)-2,2,5,5-tetramethyl-1-pyrrolidono-1-oxyl and 4-(2-bromoacetamido)-2,2,6,6-tetramethylpiperidino-1-oxyl detectable from electron spin resonance specta. 2. Hydralazine, especially in the presence of Fe2+ induced formation of thiobarbituric acid (TBA)-reactive DNA
