DESCRIPTION

Application

Ultra-low Range Molecular Weight Marker (M.W. 1,060-26,600) has been used as a protein marker in sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) and western blot.

Biochem/physiol Actions

The ultralow range marker is designed for use in the Tris-Tricine SDS-PAGE method when stained with Brilliant blue G (non-methanol based). Glutaraldehyde fixing is recommended with the ultralow marker in order to keep the two smallest proteins fixed in the gel. The ultralow range marker is supplied as a liquid, which must be diluted (1:20) with the supplied sample buffer prior to loading.

Physical form

Solution in 0.1 M Tris-HCl, pH approx. 8.5, with 4 mM EDTA, 3 mM sodium azide and 40% glycerol
