1) 货号: ZZR-H-A-357;  2) 英文品名: Hyaluronate-Hydrazide, MW 2,500kDa ;  3) 中文品名: 透明质酸酯-酰肼, MW 2,500kDa ;  4) 规格: 100mg/500mg/1g;  5) 描述: Hyaluronic Acid is functionalized with hydrazide groups using a short linker adipic acid dihydrazide (ADH). Purity: >95% powder. Degree of substitution: 5 mol % substitution. Hydrazide is a reactive group specific for aldehydes resulting in acyl hydrazone linkages, and can be used in the linking of glycoproteins or carbohydrates in a site specific fashion following periodate oxidation. Hydrazide coupling may be performed at relatively low pH such as 5.0 to avoid competition reaction by primary amines. HA-Hydrazide with higher or lower hydrazide substitution ratio (e.g. 1% and 10%) may be offered through custom synthesis service.
