Source：This product is a mixture of seven highly purified pre-stained proteins ranging from 40 kDa to 275 kDa. The 275 kDa and 72 kDa bands are orange, 50 kDa band is green, and other bands are blue. It is designed for observing protein separation during SDS-PAGE, verifying western transfer efficiency on membranes, and approximating the size of proteins.
