General description

SYBR Green I is a proprietary asymmetrical cyanine dye, which is used to detect nucleic acids. It consists of a N-alkylated benzothiazolium or benzoxazolium ring system, that is joined by a monomethine bridge to a pyridinium or quinolinium ring system. SYBR Green I binds to the minor groove of dsDNA and is excited at a wavelength of 480 nm. It has a peak fluorescence emission of 520 nm.

Application

SYBR Green I nucleic acid gel stain has been used for:
  • the quantification of dsDNA
  • to stain DNA in polymerase chain reaction (PCR)
  • for comet assay technique
  • to assess spermatozoon membrane integrity
  • for visual inspection of DNA amplified by loop-mediated isothermal amplification (LAMP)[1]
  • as a fluorescent dye in flow cytometry[2]
  • real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) for staining reverse-transcribed cDNA[2]

Features and Benefits

  • An ultrasensitive stain for post-electrophoresis staining of dsDNA in agarose or polyacrylamide gels
  • It can also detect ssDNA and RNA in denaturing agarose/formaldehyde and polyacrylamide/urea gels without any pre-washing steps
  • It is less mutagenic than ethidium bromide in Ames tests
  • It provides 50-100 times greater detection sensitivity than ethidium bromide for oligonucleotides
  • Useful for many applications with a limited amount of DNA
  • The binding of SYBR Green I to DNA does not inhibit the activity of many common restriction endonucleases, including Hind III and EcoR I
  • Removal of this stain in-gel digestion and ligation techniques is not needed
  • SYBR Green I is a greener alternative product to ethidium bromide for staining

Preparation Note

Store the product at –20 °C. The diluted Staining Solution may be stored, protected from light, either at 2–8 °C for several weeks or at room temperature for 3–4 days.

Questions

1–5 of 5 Questions  
  1. Which final concentration is recommended for staining PCR products in agarose gel with UV transiluminator from de 10000x S9430 stock?

    1 answer
    1. It is suggested to prepare the staining solution with a 1:10,000 dilution of this product in one of the following buffers:
      • 1x TE buffer (10 mM Tris-HCl with 1 mM EDTA, pH 8.0)
      • 1x TBE buffer (89 mM Tris base, 89 mM boric acid, and 1 mM EDTA, pH 8.0)
      • 1x TAE buffer (40 mM Tris-acetate with 1 mM EDTA, pH 8.0)
      Note: The buffer should not have been used previously for electrophoresis for optimal results. For optimal sensitivity, verify that the pH is between 7.5 and 8.0 (preferably pH 8.0) as SYBR Green I is pH sensitive.

  4. Will Product S9430, SYBR® Green I nucleic acid gel stain, stain DNA that contains deaza-G modified nucleotides in place of guanisine?

    1 answer
    1. Product S9430, SYBR® Green I nucleic acid gel stain, will poorly stain DNA containing deaza-G modified nucleotides in place of guanisine.  A way around this issue would be to use a mixture of deaza-G modified nucleotides with guanisine.  This will allow for better staining.
