Description

Dextran Phosphate is a chemically modified polysaccharide derivative where phosphate groups are covalently bound to the dextran backbone, significantly altering its physicochemical and biological properties. This modification is critical for creating materials with enhanced binding capacity for metal ions and improved biocompatibility for advanced applications. It serves as a key functional biopolymer in the pharmaceutical, biomedical research, and diagnostic industries, where precise molecular interactions are required.

Application

• Pharmaceutical Excipient: Used as a controlled-release matrix or stabilizer in drug delivery systems.
• Biomedical Research: Acts as a model compound for studying polyelectrolyte behavior, protein interactions, and macrophage activation.
• Diagnostic Reagents: Employed in the formulation of agglutination tests and as a component in some clinical assay buffers.
• Chromatography Media: Serves as a base material for ion-exchange resins used in protein and nucleic acid purification.
• Metal Chelation & Separation: Utilized for the selective binding and removal of heavy metal ions from solutions in environmental or analytical processes.
• Cell Culture & Tissue Engineering: Functions as a component of hydrogels or scaffolds to modulate cell growth and differentiation.
