    Abstract: PURPOSE: A method for preparing a hyaluronic acid-protein conjugate is provided to control aldehyde substitution rate of hyaluronic acid-aldekyde derivatives. CONSTITUTION: A method for preparing a hyaluronic acid-protein conjugate comprises a step of reacting protein N-terminal with hyaluronic acid-aldehyde derivative in which an aldehyde group is introduced in hyaluronic acid or salt thereof. The hyaluronic acid-aldehyde derivative is prepared by reaction of hyaluronic acid or salt thereof with oxidizer. The oxidizer is periodate. A reagent which induces reduction amination is sodium cyannoborohydride(NaBH_3CN) or sodium triacetoxyborohydride(NaBH(OCOCH_3)_3).

    Abstract translation: 目的:提供一种制备透明质酸 - 蛋白质结合物的方法,以控制透明质酸 - 醛酸衍生物的醛取代率。 构成:用于制备透明质酸 - 蛋白质缀合物的方法包括将蛋白质N-末端与透明质酸 - 醛衍生物反应的步骤,其中将醛基引入透明质酸或其盐。 透明质酸 - 醛衍生物通过透明质酸或其盐与氧化剂的反应来制备。 氧化剂是高碘酸盐。 诱导还原胺化的试剂是氰基硼氢化钠(NaBH 3 CN)或三乙酰氧基硼氢化钠(NaBH(OCOCH 3)3))。
