Product Description

Nucleic Acid Dye Green I is an asymmetric cyanine dye that specifically binds to dsDNA. Frequently used dye in qPCR and is further used as a stain for in-gel visualization of DNA. Also used in the detection of amplification products in Loop-Mediated Isothermal Amplification (LAMP) assays; this method has been used for the detection of SARS-CoV-2 virus. When bound to dsDNA the fluorescence intensity is 1000-fold greater than when in the unbound form. Does not require washing or de-staining steps. Compatible with all commonly used fluorescence detection systems. Excitation maximum = 495 nm; emission maximum = 520 nm.

This product is sold as a DMSO stock.

Usage Information

  • Supplied as a 10,000x concentrate in DMSO.
  • Soluble in TE (10 mM Tris-HCl, 1 mM EDTA, pH 8.0), TBE, or TAE buffer.
  • Verify that the pH of the staining solution, at the temperature used for staining, is between 7.5 and 8.0 (preferably pH 8.0).
  • Use diluted samples within 24 hours to ensure maximal sensitivity.
