Code:02-440
Prestained Protein Ladder Broad Range (12-270 kDa) is a mixture of highly purified proteins covalently coupled to a blue dye that resolves into 8 bands when electrophoresed. The covalent coupling of the dye to the proteins affects their electrophoretic behavior on SDS-PAGE gels relative to unstained proteins. The apparent molecular weights of the Prestained Protein Ladder bands were determined on 10–20% Tris-glycine SDS-PAGE gels by comparison to the Protein Ladder (BioAcademia 02-460 Protein Size Marker). The Prestained Protein Ladder is suited for use in SDS-PAGE and western blotting applications. It allows continuous monitoring of protein separations during electrophoresis and also provides a quick and easy way to assess blotting efficiency.
