title: Ethidium bromide in the detection of antibodies to DNA and of circulating DNA by two-stage counterimmunoelectrophoresis.
abstract: In an attempt to overcome the limitations of counterimmunoelectrophoresis in the detection of precipitating anti-DNA antibodies or circulating DNA, ethidium bromide has been used to increase the visibility of the precipitin lines and to confirm their specificity.
