Abstract
The immunochemical specificity of the immunofluorescent Crithidia luciliae method for detection of antibodies to doubleβstranded DNA (dsDNA) was confirmed by demonstrating abolition of staining by DNase digestion and by absorption with dsDNA. This method was less sensitive than a Millipore filter method for detecting antibodies to DNA. It was positive only in subjects with systemic lupus erythematosus or drugβinduced antinuclear factors. This technique appears suitable for study of the immunochemical characteristics of antibodies to dsDNA.
