Abstract
Patients (5) with clinical features of a connective tissue disease most suggestive of systemic lupus erythematosus had a negative ANA [anti-nuclear antibody] by conventional screening at 1/20 dilution on mouse liver. Significant titers of antibodies to single-stranded DNA were detected using a double antibody radioimmunoassay. Certain patients have antibodies to DNA restricted to single-stranded determinants as detected by radioimmunoassay with single-stranded DNA as antigen and a negative ANA test.
