Determination of nucleic acids using rivanol as the fluorescent probe in the presence of SDS

The quantitative method for nucleic acids using rivanol as the fluorescent probe in the presence of SDS was proposed. Under proper conditions, addition of nucleic acids to a mixture of rivanol and SDS resulted in enhanced fluorescence and spectral shifts of rivanol-SDS system. The calibration graph was linear in the range of 0-10.0 mug/ml for CT DNA and 0-9.0 mug/ml for yeast RNA, the limit of detection was 62 ng/ml for CT DNA and 156 ng/ml for yeast RNA. CT DNA could be determined in the presence of 20%(w/w) yeast RNA.
