    • PURPOSE: An immobilization method of bone morphogenetic proteins is provided to minimize immune reactions after bone graft by using a natural calcium chelating agent, to have excellent engraftment rate, and to improve cell suitability, biological suitability, and hydrophilicity, thereby inducing a fast bone growth. CONSTITUTION: An immobilization method of bone morphogenetic proteins comprises: a step of forming a coating layer on the surface of an implant; a step of combining chitosan or alginate as a natural calcium chelating agent on the coating layer; a step of immobilization of bone morphogenetic proteins by using diphenylphosphoryl azide, hexamethylene isocyanate, succinimide, carbodiimide glutaraldehyde or ethyl dimethylaminopropyl carbodiimide-crosslinked reagent; a step of forming hydroxyapatite or beta-tricalcium phosphate coated on the surface of titanium. The bone morphogenetic protein is selected from a group consisting of BMP-2, BMP-4, and BMP-12.
    • 目的:提供骨形态发生蛋白的固定化方法,通过使用天然钙螯合剂使骨移植后的免疫反应最小化,植入率优异,提高细胞适应性,生物适应性和亲水性,从而诱导快速骨生长 。 构成:骨形态发生蛋白的固定化方法包括:在植入物的表面上形成被覆层的步骤; 将壳聚糖或藻酸盐作为天然钙螯合剂结合在涂层上的步骤; 使用二苯基磷酰基叠氮化物,六亚甲基异氰酸酯,琥珀酰亚胺,碳二亚胺戊二醛或乙基二甲基氨基丙基碳二亚胺交联试剂来固定骨形态发生蛋白的步骤; 在钛表面上形成羟磷灰石或磷酸三钙的步骤。 骨形态发生蛋白选自BMP-2,BMP-4和BMP-12。
