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.
Lambda Markers
These DNA markers are used to determine size of unknown DNA fragments. If using within 2–3 days, they do not need to be refrigerated and can be stored right on a shelf. If storing for longer time periods, freezing is recommended.
Ship date is required.
