It is an object of the present invention to provide a method of conveniently efficiently and easily immobilizing a protein on a substrate, a method of detecting a substance capable of interacting with the protein at a high sensitivity, and a protein and a protein-immobilized substrate which are used in these methods.
In the method of detecting a substance capable of interacting with a protein using the immobilized protein of the present invention, a protein bound to a compound having a group capable of binding onto a substrate for immobilizing a biomolecule or a carrier provided on the substrate and immobilized onto the substrate, is used as the immobilized protein.
本发明的目的是提供一种方便、高效、简易地将蛋白质固定在基质上的方法,一种高灵敏度地检测能与蛋白质相互作用的物质的方法,以及在这些方法中使用的蛋白质和蛋白质固定基质。
在使用本发明的固定化蛋白质检测能与蛋白质相互作用的物质的方法中,使用与具有能结合到基底上的基团的化合物结合的蛋白质作为固定化蛋白质,以固定
生物大分子或提供在基底上并固定在基底上的载体。
