• Broad range size estimation(7-240kDa)
• Highly purified and blended 10 recombinant proteins
• User oriented ready to use solution

Description

LandMark™ broad range prestained protein marker(dual color) is a dual color prestained size marker. It is a mixture of 10 recombinant purified and prestained polypeptides whose molecular weights are well-adjusted ranging from 7,000 to 240,000 Da. It is provided preblended in a ready-to-use formula and no reconstitution or further dilution is necessary before use. A blue and pink chromophore is covalently bound to proteins, and 10 prestained proteins are visible during electrophoresis or electrophoretic transfer from the gel to a membrane. The 25 KDa and 70 KDa proteins labeled with orange chromophore offer easy identification and serve as a landmark. Because coupling of chromophore to the proteins affects their apparent molecular weights in SDS-PAGE, unstained protein standard should be used for accuracy >95%.
