Examples include chitosan, hyaluronic acid, and dextran. Injectable forms include iron dextran and iron sucrose. Solubilization of C3 fragments deposited on crosslinked dextran gel beads. Such polysaccharides include pectin, dextran, agar, and xanthan. Polyvinyl alcohol, guar gum, dextran gums, and urea-formaldehyde resins are the typical gelling agents. An uncommon but significant complication of dextran osmotic effect is acute kidney injury. Acetalated dextran is structurally different from acetylated dextran. All species within this genus are heterofermentative and are able to produce dextran from sucrose. It is in complex with gluconate, dextran, carbonyl iron, and other salts. Efforts have been made to develop modified dextran polymers. For this, a bait ligand is immobilized on the dextran surface of the SPR crystal. The generic name of Cosmofer is low molecular weight iron dextran. The use of high molecular weight iron dextran has now been abandoned. Sephadex is a cross-linked dextran gel used for gel filtration. A vivid characterization is to measure the rejection of dextran blue or other colored molecules.
