Abstract
Actinomycin D is an antitumor antibiotic which intercalates within DNA. The interaction of actinomycin D with double-stranded and thermally denatured (single-stranded) calf thymus DNA was studied in solution as well as at the electrode surface using differential pulse transfer voltammetry with carbon paste electrode in 0.2 M acetate buffer, pH 5.0.
