YMC-Pack Diol-SEC

Our best-selling size exclusion chromatography column (YMC-Pack Diol-SEC) utilizes a silica gel base with high resistance to pressure, which is suitable for size exclusion separation of sugars, proteins, peptides and nucleic acids in order to determine molecular weight.

YMC-Pack Diol-SEC columns come in four pore sizes, starting with Diol-60, suitable for the separation of peptides of oligosaccharides with molecular weights that are 10,000 or less. The larger pore sizes, Diol-120, Diol-200, and Diol-300 are suited to the separation and/or size determination of proteins whose molecular weights range from 10,000 to several hundred thousand Daltons. The 200 and 300Å pore size columns are ideal for the analysis of antibody drugs and other large molecule biopharmaceuticals.

When size exclusion columns are necessary to determine the size of neutral sugars and/or water-soluble compounds with high molecular weights, all four sizes of YMC-Pack Diol-SEC can be used individually as well as in combination.
