Description

Mbiotech's Step-view¢â 20KD prestained protein molecular weight standard is a dual color prestained standard. It is a mixture of 8 recombinant purified and prestained polypeptides whose molecular weights are well-adjusted. 20KD prestained protein molecular weight standard is available in a ready-to-use formula (no need to boil before use), and is suitable for sizing proteins between 20,000 and 140,000 Da by SDS-PAGE. A blue and pink chromophore is covalently bound to proteins, and 8 prestained proteins are visible during electrophoresis or electrophoretic transfer from the gel to a membrane. The 40 and 100 Kda proteins are labeled with pink chromophore. Because coupling of chromophore to the proteins affects their apparent molecular weights in SDS-PAGE relative to unstained proteins, unstained protein standard (Cat. No. 20021) should be used for accuracy >95%.
