A stimuli-responsive, hybrid hydrogel wherein the bulk of the polymer is made up of relatively inexpensive water soluble polymer strands crosslinked by protein domains. The responsiveness of the gel is controlled or modulated by the protein component.
The physical and biological properties of the hydrogel are determined by specifically designed or engineered protein domains.
The crosslinking of the protein domains to the water soluble polymers is by means of non-covalent bonding such as chelation or coordination bonding, biotin-avidin bonding, protein—protein interaction and protein-ligand interaction, or by means of covalent bonding. Methods of making and using the polymer-protein hydrogels are disclosed in this application.
一种刺激响应型混合水凝胶,其中聚合物的大部分由相对廉价的水溶性聚合物链通过蛋白结构域交联而成。凝胶的响应性由蛋白组分控制或调节。水凝胶的物理和生物特性由特定设计或工程化的蛋白结构域确定。蛋白结构域与水溶性聚合物的交联是通过非共价键合,如螯合或配位键合,生物素-亲和素键合,蛋白-蛋白相互作用和蛋白-配体相互作用,或通过共价键合。本申请公开了制备和使用聚合物-蛋白水凝胶的方法。
