Product Information

GeneStep™ 50bp DNA Ladder

Catalog No : 301105 | Pack Size : 0.5 mL
Catalog No : 301106 | Pack Size : 5 mL

A unique combination of PCR products and a number of proprietary plasmids digested with appropriate restriction enzymes to yield 17

fragments, suitable for use as molecular weight standards for agarose gel electrophoresis. The DNA includes fragments ranging from 50-1,500

base pairs. The 200, 500 and 1200 base pair bands have increased intensity to serve as reference points. The approximate mass of DNA

in each band is provided (0.56 μg a load) for approximating the mass of DNA in comparably intense samples of similar size.

Range: 50-1,500 base pairs

Number of Bands: 17

Concentration: 112 μg / ml

Recommended Load: 5 μl / well

Containing orange G as tracking dyes

Source : 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 10mM EDTA.
