BR Prestained Protein Ladder B (10-180 kDa)

The BR Prestained Protein Ladder B, is a combination of 10 pre-stained proteins with molecular weights from 11 to 180 kDa. The 10 recombinant proteins are covalently coupled with blue chromophore, while 1 green band at 25 kDa and a red band at 75 kDa, serve as reference bands. The Prestained Protein Ladder B, keeps track of the size and separation of proteins during SDS-polyacrylamide gel electrophoresis, approximating protein size, and validating Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes.
