Full-Range Molecular Weight Marker, Biotinylated (Catalog # MW001)
This preparation contains a mixture of seven individually biotinylated proteins (rat Phosphorylase-b, bovine Catalase, recombinant human Annexin V, recombinant human IL-6, recombinant human TNF-alpha, bovine Cytochrome c, and recombinant human EGF) and one blue dye-conjugated protein (recombinant human Annexin V). The molecular weights of the biotinylated proteins were determined by Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS). The molecular weight of the blue protein was derived from a calibration curve using the biotinylated markers. This product is designed for use as molecular weight markers in Western blots probed with enzyme-conjugated avidin or streptavidin. |

Prestained Blue Molecular Weight Marker (Catalog # MW002)
This preparation contains a mixture of seven individually blue dye-conjugated proteins (rat Phosphorylase-b, BSA, bovine Catalase, recombinant human Annexin V, Trypsin Inhibitor, recombinant human TNF-alpha, and Aprotinin). The molecular weights of the prestained proteins were individually calibrated against the non-stained protein marker standards. This product is designed for use as prestained molecular weight markers in Western blots. |
