The Thermo Scientific GeneRuler 50 bp DNA Ladder is recommended for 50 bp to 1,000 bp on agarose or polyacrylamide gels Sizing and approximate quantification of double-stranded DNA within a range. DNA molecular weight standards consist of 13 DNA fragments and contain 6X TriTrack DNA loading dye.

Features of the 50 bp DNA Ladder
• Easy Visualization—Three-color DNA mobility tracking during electrophoresis using 6X TriTrack DNA Loading Dye (Contains xylene cyanine FF, bromophenol blue and orange G)
• Simplicity—one loading dye for a variety of samples
• Bands are obvious b>—Clear results from a mixture of individual DNA fragments purified by chromatography

Product Usage
This double-stranded DNA molecular weight standard is compatible with 1–2% standards and Precast agarose slab gels for visualization after ethidium bromide or SYBR Safe staining. Due to the uniform band intensity and bright reference band, sizing and orientation can be easily performed. A defined amount of DNA in each band allows for approximate quantification of sample DNA.
