10-170 kDa Protein Marker (Stained)

10-170 kDa Protein Marker (Stained)

10-170 kDa Protein Marker (Stained) is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verifying of Western transfer efficiency on PVDF, nylon and nitrocellulose membranes and approximate sizing of proteins. It is composed of prestained recombinant prokaryotic proteins. Prestained Protein Molecular Weight Marker is a three-color molecular weight standard, contains 10 prestained natural proteins with molecular weights from 10 kDa to 170 kDa. It has two reference bands: a 70 kDa orange band and a 10 kDa green band.

62.5 mM Tris-H₃PO₄, pH 7.5 at 25°C, containing 1 mM EDTA, 2% SDS, 10 mM DTT, 1 mM NaN3 and 33% glycerol.
