Size Exclusion Resins

Size exclusion resins are used in packing columns for size exclusion chromatography (SEC). This technique, also known as molecular sieve chromatography or gel filtration chromatography, separates molecules in a mixture according to their size or molecular weight. It is commonly used to separate proteins, peptides, antibodies, and water-soluble polymers. Size exclusion resins contain pores of varying sizes and can be made by packing beads closely. SEC resins are generally composed of various polymers, such as agarose, dextran, and polyacrylamide. Visit the supplier page for more information, such as the appropriate target size range.
