Size exclusion chromatography(SEC), also known as gel filtration chromatography or steric exclusion chromatography, is a protein isolation technology based on the various molecular weights and shapes of bio-molecules.

IEX resins can be divided into cation exchange resin and anion exchange resin according to the property of electric charges on functional groups.

Glutathione S-transferase (GST) is a multifunctional phase II metabolic enzyme and a macromolecular protein with a molecular weight of 26kDa.

To put it simply, blue resin is an affinity resin using Cibacron Blue 3GA dye molecules as ligands.

Diamond Protein L is a novel affinity chromatography resin obtained by coupling Protein L ligands on highly rigid agarose beads.

The majority of currently available insulin is obtained via genetic engineering synthesis and subsequent purification process, among which, chromatographic technology is most widely used.

As early as 1840s, scientists discovered cytoplasmic genetic factors which can metastasize among cells.

Binding capacity refers to the amount of target molecules a type of resin can bind under certain condition.
