Dextran Chromatography

Dextran Chromatography is an important technique in biochemistry and molecular biology. It is used to separate and purify macromolecules such as proteins, nucleic acids, as well as carbohydrates and other biomolecules. The process takes advantage of the fact that individual molecules have different sizes and shapes and that they partition differently when they are subjected to a high pressure gradient in a specifically designed column. The technique is widely used for the purification of biopolymers systems, like enzymes, antibodies, and viruses, for structural studies and for the analysis of complex mixtures. It has become an essential tool for modern biotechnology and protein engineering.
