The present invention relates to a polybifunctional reagent having a polymeric backbone, one or more pendent photoreactive moieties, and two or more pendent bioactive groups. The reagent can be activated to form a bulk material or can be brought into contact with the surface of a previously formed biomaterial and activated to form a coating. The pendent bioactive groups function by promoting the attachment of specific molecules or cells to the bulk material or coated surface. Bioactive groups can include proteins, peptides, carbohydrates, nucleic acids and other molecules that are capable of binding noncovalently to specific and complimentary portions of molecules or cells.
本发明涉及一种具有聚合物骨架、一个或多个下垂光活性分子和两个或多个下垂
生物活性基团的多官能团试剂。该试剂可以活化形成块状材料,也可以与先前形成的
生物材料表面接触并活化形成涂层。悬垂
生物活性基团通过促进特定分子或细胞附着到主体材料或涂层表面来发挥作用。
生物活性基团可包括蛋白质、肽、
碳水化合物、核酸和其他能够与分子或细胞的特定和互补部分非共价结合的分子。
