Color Prestained Protein Standard, Broad Range (10-250 kDa)

A mixture of highly pure, recombinant, prestained proteins, covalently coupled with a blue chromophore, and two reference bands (one orange and one green at 72 kDa and 26 kDa, respectively), that resolves into 11 sharp bands when electrophoresed. The Color Prestained Protein Standard is designed for observing protein separation during SDS-PAGE, verification of western transfer efficiency on membranes, and for approximating the size of proteins. The Color Prestained Protein Standard may also be used in fluorescent imaging of SDS-PAGE.
