BR Prestained Protein Ladder D (5-245 kDa)

The BR Prestained Protein Ladder D is a combination of 13 pre-stained proteins with molecular weights from 5 to 245 kDa. The 13 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 D 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.
