Molecular Weight Markers
Molecular-weight size markers are a set of standards used to identify the approximate size of a molecule run on a gel during electrophoresis, using the principle that molecular weight is inversely proportional to migration rate through a gel matrix. The molecular weight markers offered are ideal for verification of PCR products, for size analysis of digested DNA, and easy band identification of a number of different fragments. Certain models are available pre-mixed with loading dye.

Amersham ECL DualVue Western Blotting Markers, Cytiva
Supplier: Cytiva
Amersham™ ECL™ DualVue™ Western blotting markers perform two key functions. Firstly, the prestained marker proteins confirm protein transfer in addition to clearly defining blot orientation. Secondly, the recombinant tagged proteins are detected on film or by CCD imaging in conjunction with the target protein(s) of interest, enabling highly accurate molecular mass determination of the target protein(s). The tagged markers are detected easily and specifically by means of a specific conjugate that eliminates any cross contamination between target protein(s) and markers.
