Prestained Protein Ladder contains 13 prestained recombinant proteins that cover a wide range of molecular weights from 3.5kDa – 245kDa. An orange reference band of ~75kDa and a green reference band of ~25kDa provides easy monitoring of protein separation. The ladder is ready-to-use. No further dilution, addition of a reducing agent or heating is required.
