title: Enzyme-linked immunosorbent assay for use with nuclear protein-DNA complex antigens.
abstract: An enzyme-linked immunosorbent assay (ELISA) was developed for identification and quantification of nuclear antigens (nonhistone protein-DNA complexes from chromatin). Until now, the complement fixation assay has been the only immunoassay routinely applied to nonhistone protein-DNA complexes. The ELISA is considerably more sensitive than the micro-complement fixation test for assaying the immunospecificity of nuclear protein-DNA complexes. Dilutions of rabbit antisera as great as 1:6400 could be used to detect nanogram quantities of antigen, chicken reticulocyte chromatin or dehistonized rat liver chromatin.
