SYBR™ Green I Nucleic Acid Gel Stain is one of the most sensitive stains available for detecting double-stranded DNA (dsDNA) in agarose and polyacrylamide gels. Because SYBR™ Green I has greater sensitivity for dsDNA, it is especially useful for assays where the presence of contaminating RNA or ssDNA might obscure results. With exceptionally low background fluorescence and spectral characteristics that closely match light sources and filter sets in existing instruments, SYBR™ Green I stain is ideal for use with laser scanners. One mL stains 100 minigels.
