title: [Studies on the specificity of an antiserum against denaturated DNA from Sarcina maxima].
abstract: An antiserum against denatured DNA from Sarcina maxima (71% (A + T)) reacted in complement fixation tests with denatured DNA's of various sources. The serological activity of the antibodies is in correlation with the (adenine + thymine)-content of the DNA's used as antigens. Haptene inhibition tests demonstrate a preferable reaction of the antibodies with T2-sequences. The heterogeneity of DNA-antisera and the increasing specificity of such antisera, if DNA with high (A + T) or (G + C)-content served as immunogen, are discussed.
