Broad Multi Color Pre-Stained Protein Standard is a special-designed protein standard. The standard is a mixture of ten highly purified prestained proteins ranging from 5 kDa to 270 kDa, covalently coupled with four different chromophores. The 30 kDa band is red, 50 kDa band is green, 270 kDa band is orange, and other bands are blue. Broad Multi Color Pre-Stained Protein Standard is designed for observing protein separation during SDS-PAGE, verifying western transfer efficiency on membranes, and approximating the size of proteins.

WB-MASTER Protein Standard is designed for convenient protein identification in western blot. This standard consists of seven recombinant proteins with molecular weight of 20 kDa, 30 kDa, 40 kDa, 50 kDa, 60 kDa, 80 kDa and 120 kDa. Each of the proteins contains an IgG binding site that is able to bind to primary or secondary antibodies derived from a wide range of host species. The standard thus enables direct visualization of both the protein marker and users’ samples on the same western blot membrane without any additional reagents.
