Prestained Protein Ladder (25-400 kDa)

Prestained Protein Ladder is a mixture of 10 blue-, red-, orange-, green-stained proteins (25 to 400 kDa) for use as size standards in protein electrophoresis (SDS-PAGE) and western blotting. The protein ladder is supplied in a ready-to-use format for direct loading onto gels; no need to heat, reduce, or add sample buffer prior to use.
