dsGreen, an analog of SYBR® Green I, is a very sensitive dsDNA detection dye. High sensitivity, and high selectivity for dsDNA allow to use dsGreen as a universal dsDNA detection reagent for qPCR. No need to use labeled probes to detect amplification with dsGreen – unlabeled primers are sufficient.

Unlike other preparations of dsGreen provided by Lumiprobe for gel staining purposes, this formulation is specially designed to be used in real-time PCR experiments. Specific features are:

  • Concentration of the dye is optimized for qPCR and carefully adjusted for reproducible results from lot to lot.
  • PCR tested preparation – quality guaranteed
  • Low fluorescence background – high fluorescence intensity gain

Note: fluorescent properties of dsGreen bound to dsDNA below are taken from the following publication: Zipper, H.; Brunner, H.; Bernhagen, J.; Vitzthum, F. Investigations on DNA intercalation and surface binding by SYBR Green I, its structure determination and methodological implications. Nucleic Acids Res., 2004, 32, e103.
