Description
Application A proprietary unsymmetrical cyanine dye which is an ultrasensitive stain for post-electrophoresis staining of dsDNA in agarose or polyacrylamide gels. SYBR Green I can also be used to detect ssDNA and RNA in denaturing agarose/formaldehyde and polyacrylamide/urea gels without any prewashing steps, although the sensitivity is lower (approximay 100 to 300 pg per band using 254 nm epi-illumination). SYBR Green II is recommended for ss-DNA and RNA.
SYBR Green I stain has been shown to be much less mutagenic than ethidium bromide in Ames tests. SYBR Green I is also a very sensitive stain for oligonucleotides, allowing for detection of as little as 1-2 ng of a synthetic 24-mer on a 5% polyacrylamide gel, which is 50-100 times greater sensitivity than obtained with ethidium bromide. Staining agarose gels with SYBR Green I does not interfere with the transfer of nucleic acids to membranes or subsequent hybridization in Southern or Northern blot analysis as long as 0.1%-0.3% SDS is included in prehybridization and hybridization buffers to remove the dye.
