This exceptionally sensitive nucleic acid gel stain has bright fluorescence when bound to dsDNA and low background in gels, making it ideal for detecting dsDNA in gels using laser scanners or standard UV transilluminators. SYBR Green I nucleic gel acid stain has also found uses in capillary electrophoresis, real-time PCR assays and bandshift assays. One mL stains 100 minigels. A 500 µL unit size (S-7563) and a special packaging (S-7585) are available.
