The MagicMark™ XP Western Protein Standard is specifically designed for easy and convenient protein molecular weight estimation directly on Western blots. The standard consists of 9 recombinant proteins, each of which contains an IgG binding site. The IgG binding site binds the primary or secondary antibody used for detection of the target protein, allowing direct visualization of the standard on the Western blot.

The MagicMark™ XP Standard is compatible with all Western kits and substrates (chemiluminescent, chromogenic, and fluorescent) and offers:

• Direct visualization of molecular weight standard bands on Western blots with the commonly used immunodetection methods
• Nine sharp clear bands in even increments from 20–220 kDa
• Convenient, ready-to-use format—no mixing, reducing, or heating

The bands can also be visualized with Coomassie or membrane stains, if needed.
For Research Use Only. Not for use in diagnostic procedures.
