10-200kDa Wide Range Protein Molecular Weight Unstained Marker is designed for accurate sizing of proteins in SDS-polyacrylamide gel electrophoresis, as well as western blot on PVDF, nylon and nitrocellulose membranes.

10-200kDa Wide Range Protein Molecular Weight Unstained Marker is a mixture of 14 recombinant, highly purified, unstained proteins ranging in size from 10kDa to 200kDa. 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.
