IRIS9 Prestained Protein Ladder (9 pre-stained bands, 15-180 kDa)

The BR Prestained Protein Ladder E is a combination of 9 pre-stained proteins with molecular weights from 15 to 180 kDa. The 9 recombinant proteins are covalently coupled with blue chromophore, while 2 red bands at 70 kDa and 30 kDa, a green band at 15 kDa and a newly designed peacock green band at 60 kDa serve as reference bands. The BR Prestained Protein Ladder E keeps track of the size and separation of proteins during SDS-polyacrylamide gel electrophoresis, approximating the target protein size and validating the Western transfer efficiency on PVDF, nylon, or nitrocellulose membranes.
