The unstained protein standard, broad range is a mixture of highly pure, recombinant proteins that resolves into 13 sharp bands from 10 to 200 kDa when electrophoresed and stained with Coomassie Brilliant Blue R-250 or other commercially available, ready-to-use protein stains.

• Allows accurate molecular weight determination when performing SDS-PAGE analysis
• Direct loading, additional loading buffer and heat incubation not required
• Recombinant proteins with no detectable protease contaminating activities
• Optimal stability for up to 24 months
