12-80 kDa Protein Marker. Protein Marker I is composed of five unstained recombinant proteins 20 kDa, 30 kDa, 40 kDa, 60 kDa, 80 kDa and one blue prestained recombinant protein 12 kDa. Prestained protein is obvious to monitor electrophoresis. 40 kDa band is a double intensity band for convenient identification of protein molecular weight. MW range from 12 kDa to 80 kDa. Ready-to-use format, no heating and reductant are required.
