Description

Description:

A mixture of special plasmid and phage DNAs hydrolyzed by specific enzymes, resulting in 14 fragments suitable for use as molecular weight standards in agarose gel electrophoresis.

Fragment Sizes:

Fragment Length, bp DNA Mass, ng Fragment Length, bp DNA Mass, ng
39936 80 4000 70
24730 70 3000 160
15206 40 2500 80
10000 70 2000 60
8000 70 1500 80
6000 70 1000 50
5000 70 500 30

Storage Conditions: 10 mM Tris-HCl (pH 7.5); 1 mM EDTA; 50 mM NaCl. Store at -20°C.

Note:

This DNA ladder is not intended for DNA quantification, but can be used for approximate estimation by comparing the intensity of fragments of the same size.
We recommend loading 0.5–1 µg of DNA marker per lane.
Before use, add 1/10 volume of loading buffer with dye to the DNA marker.
The marker with dye can be stored at 4–8°C for up to 6 months.
