The Color prestained protein standard, broad range is a mixture of highly pure, recombinant, prestained proteins, covalently coupled with a blue chromophore, and two reference bands (one orange and one green at 72 kDa and 26 kDa, respectively), that resolves into 11 sharp bands when electrophoresed.

• Allows approximate molecular weight determination when performing SDS-PAGE analysis
• Applications include verification of Western transfer efficiency and fluorescent imaging of SDS-PAGE
• Direct loading, additional loading buffer and heat incubation not required
• Recombinant proteins with no detectable protease contaminating activities
