Think green with Nancy-520!
The Safer, Stable Alternative to Ethidium Bromide and SYBR® Green
|
 |
Nancy-520 fluorescent stain is specific for double-stranded DNA in agarose and polyacrylamide gels.
 |
• Less mutagenic than SYBR Green I (Ames test)
• Higher sensitivity than ethidium bromide |
| |
Ames II mutagenicity assay performed using Ethidium bromide (blue), SYBR Green I (red) and Nancy-520 (green). Nancy-250 produces fewer frame shift or base-pair substitution mutations than either ethidium bromide or SYBR Green I. |
 |
• Fast and robust staining with less photobleaching
• Excitation/Emission settings similar to SYBR Green I
– no additional filters or light source needed |

DNA marker (Lambda DNA Hind III digest) at 200 ng/lane (left) and 20 ng/lane (right) was separated on a 1% agarose gel, stained with either Nancy-520 or SYBR Green I post-electrophoresis, and imaged. Nancy-520 produces sharp, clear bands with detection down to 0.84 ng of DNA.

with CCD camera.
B. Nancy-520, laser scanner Fuji® FLA-3000, λex 532 nm/λem
580 nm cut-off filter.
C. SYBR Green I, λex UV screen (300 nm)/λem 590 nm bandpass
filter with CCD camera.
D. SYBR Green I, laser scanner Fuji® FLA-3000, λex 473 nm/λem
520 nm cut-off filter. |

• Suitable for dsDNA quantitation in solution
Linear detection range 0-2 µg/ml of DNA |
| |
Quantitation of DNA (Lambda DNA Pst I Digest) in solution using Nancy-520, performed in a 96 well plate. Fluorescence was measured on a laser-scanner (FLA-3000, Fuji) with 532 nm excitation and 580 nm emission filter. Different concentrations of DNA in TE buffer, pH 7.5, and their corresponding fluorescence values are shown. |
