Western Blot Protein Standard

The MagicMark™ XP Western Protein Standard employs innovative technology for easy and accurate molecular weight estimation directly on western blots. It consists of a mixture of nine proteins ranging in mass from 20 to 220 kDa (Figure 1). Each protein band contains an IgG binding site, allowing marker visualization using the same reagents (chemiluminescent, fluorescent, or colorimetric substrates) and protocol for the target protein as your immunoassay. There are no extra procedures or additional reagents involved that can increase nonspecific background on your western blots (Table 1). In addition, the non–dye-modified proteins in the MagicMark™ XP Standard result in truer molecular weight estimations and sharper band resolution than with conventional protein standards.
