Novus Biologicals™ Blu13 Prestained Protein Ladder

Description

Prestained Protein Ladder

The Blu13 Prestained Protein Ladder 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 Blu13 Prestained Protein Ladder 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.
