DNA Ladders

Products

100bp DNA Ladder H3 RTU (Ready-to-Use) (GeneDireX)

A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 12 fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 100-3,000 base pairs. The 500 and 1,500 base pair bands have increased the intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.54 μg a load) for approximating the mass of DNA in comparably intense samples of similar size.

PCR products and double-stranded DNA digested with appropriate restriction enzymes are phenol extracted and equilibrated to 10 mM Tris-HCl (pH 8.0) and 10 mM EDTA.

OneMARK 100 (Ready-to-Use) (GeneDireX)

OneMARK 100 with the Novel Green was designed to show virtually uniform spacing over a wide fragment range. The ladder is supplied in a ready-to-use format containing the fluorescent DNA stain and tracking dyes. High quantum yield and excellent stability make the fluorescence dye the ideal fluorophore for DNA staining applications and a superior replacement for the widely used dyes, ethidium bromide or SYBR® Green I. The OneMARK 100 with the Novel Green was optimized for direct loading onto unstained agarose gels. The ladders provide highest level of convenience during the routine handling and avoid commonly used gel staining procedures with ethidium bromide or SYBR® Green I. The OneMARK 100 includes fragments ranging from 100-3,000 base pairs. The 500 and 1,500 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA in each band is provided (0.54 μg per loading) for approximating the mass of DNA in comparably intense samples of similar size.

Application
• No-post-staining procession
• Direct loading onto your agarose gel for analysis
