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.
