Star Ribbon Pre-stained Protein Marker (2.7-40 kDa)

This product is a mixture of nine highly purified pre-stained proteins ranging from 2.7 kDa to 40 kDa. The 40 kDa band is orange, 10 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.
