Overview | caseous acid, also known as dextran gel G-25, is a gel made by cross-linking dextran, with three-dimensional porous network structure. The trade name sephadex is a commonly used stationary phase for size exclusion chromatography. The degree of cross-linking of the product affects the size of the pores in the network structure. Since the degree of cross-linking is often expressed in terms of water absorption, the commodity model is expressed in terms of 10 times the amount of water absorption. High water absorption and low cross-linking. Mainly used for sugar, polysaccharide, Amino sugar, peptide, protein, enzyme separation in aqueous solution. It is also used for the separation of higher molecular weight and water insoluble substances. Caseous acid is a type of dextran gel. |
uses | caseous acid is mainly used for aqueous separation of sugars, polysaccharides, Amino sugars, peptides, proteins and enzymes. Sephadex is a bead-like cross-linked dextran that contains a large number of hydroxyl groups and readily swells in water and electrolyte solutions. The G-type glucan gel has various degrees of cross-linking. Therefore, their swelling and fractionation ranges are also different. The use of molecular sieves, buffer exchange, desalination, separation of small molecules, removal of small molecules, industrial desalination. |
