ProSieve™ Protein Markers, Lonza

ProSieve®
50550 50552 193839 50547
Markers contain a set of proteins designed for accurate sizing of protein samples in SDS-polyacrylamide gels

The color markers are ideal to provide accurate confirmation of protein transfer in Western blotting. They contain nine proteins labeled with fluorescent dyes and are supplied as lyophilized solids containing the buffer salts and detergent found in the typical Laemmli buffer system. The exact masses of the proteins are 10, 15, 20, 25, 40, 50, 80, 125, 190kDa. Each lot of the colored markers is calibrated against the unstained markers for accuracy.

The recombinate proteins do not contain oligosaccharides that can cause anomalous migration, heterogeneous bands, and inaccurate size estimation. The unstained markers contain 10 proteins with known exact masses of 5, 10, 15, 25, 35, 50, 75, 100, 150, and 225kDa. The 50kDa band is double-intensity for easy identification.
