title: Conformational studies of Australia antigen by optical rotatory dispersion and circular dichroism.
abstract: The optical rotatory dispersion and circular dichroism of intact, 8 m urea- or sodium dodecyl sulfate-treated, and carbamidomethylated Australia antigen indicated that the antigen possesses a high alpha-helical content similar to human high-density lipoproteins.
