10-200kDa Wide Range Protein Molecular Weight Marker, Unstained

14 band: 10, 15, 20, 25, 30, 40, 50, 60, 70, 85, 100, 120, 150, 200kDa: BBI Wide Range Protein Molecular Weight Unstained Marker is designed for accurate sizing of proteins in SDS-polyacrylamide gel electrophoresis, as well as on PVDF, nylon and nitrocellulose membranes. BBI Wide Range Protein Molecular Weight Unstained Marker is a mixture of 14 recombinant, highly purified, unstained proteins ranging in size from 10 kDa to 200 kDa. Each protein in the ladder contains an integral Strep-tag® II sequence which can be detected directly on Western blots using a Strep-Tactin®-AP* conjugate or an antibody against Strep-tag® II. Ladder produces sharp bands on SDS-polyacrylamide gel following staining of the gel with Coomassie Brilliant Blue R-250, Silver Staining Kit or by other protein staining methods. Coomassie Blue R-250 can also be used to visualize unstained ladders and markers on PVDF membranes.
