  • Applications

    Glycogen (CAS 9005-79-2) is primarily a storage polysaccharide used in laboratory and research contexts as a biochemical reagent; it is commonly employed as a carrier to aid in the precipitation of nucleic acids in DNA/RNA isolation protocols. It also serves as a model carbohydrate in polymer science and biomaterials research for hydrogel formation and other carbohydrate-based materials. In biotech and pharmaceutical research, glycogen is used as a reference carbohydrate and, in some contexts, as a substrate or substrate mimic for carbohydrate-active enzymes. Additionally, it can be explored as a starting material for glycoconjugate chemistry and as a component in experimental biopolymer systems, subject to regulatory considerations.
