Protein Molecular Weight Marker (OORA00223)

Liquid, 1X Loading Buffer 62.5 mM Tris-HCl, pH 6.8, 2% (w/v) SDS, 250 mM NaCl, 1mM EDTA, 4% (v/v) beta-Mercaptoethanol, 35% (v/v) Glycerol and 0.05% (w/v) bromophenol blue with 0.01% (w/v) Sodium Azide

This protein molecular weight marker is a cocktail containing seven purified proteins that range in size from 14 to 120 kDa and thus span a molecular weight range common to most proteins and protein subunits. The protein mixture has been formulated to yield well-defined bands after SDS-polyacrylamide gel electrophoresis and staining with Coomassie blue or other common staining techniques. The intensity of the 67 kDa bovine albumin band has been increased to serve as a reference. The product is supplied in 1X loading buffer and is ready-to-use.
