abstract: Immunization of animals with DNA modified by a mixture of bisulphite and O-methylhydroxylamine and methylated bovine serum albumin results in production of antibodies mainly reacting with modified DNA. Antibodies that react with denatured DNA were produced in minute quantity. It was shown that elicited antibodies possess a high specificity and have the ability to recognize only nucleotides with a double modification. The immune sera were fractionated by Sephadex G-200 column chromatography and the antibody activity was demonstrable in the 19S and 7S fractions. The attempts to induce synthesis of antibodies by injection of DNA modified by O-methylhydroxylamine failed.
