IRIS9 Prestained Protein Ladder
IRIS9 Prestained Protein Ladder is a ready-to-use prestained protein molecular weight marker composed of 9 recombinant proteins ranging from 15 to 180 kDa. It is designed for real-time monitoring of protein separation during SDS-PAGE and for evaluating protein transfer efficiency in Western blot workflows.

The IRIS9 Prestained Protein Ladder 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 IRIS9 Prestained Protein Ladder 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.
