Methods for immobilizing a protein or functional protein fragment on a surface in a controlled orientation, for immobilizing a protein or functional protein fragment on a surface with efficient immobilization loading of the protein or protein fragment, and for immobilizing a protein or functional protein fragment on a surface with retention of the activity of the protein or protein fragment. In the methods, a tetrazine-modified protein or a tetrazine-modified functional protein fragment is contacted with a trans-cyclooctene-modified surface to provide a surface having the protein or functional protein fragment immobilized thereon. Surfaces having a protein or functional protein fragment immobilized thereon obtainable by the method and methods for using the surfaces for measuring the binding of a ligand to a protein or functional protein fragment.
将蛋白质或蛋白质功能片段固定在表面上的方法,以控制方向固定蛋白质或蛋白质功能片段在表面上,以高效固定蛋白质或蛋白质片段的负载,并保持蛋白质或蛋白质片段活性的方法。在这些方法中,通过将
四唑改性的蛋白质或
四唑改性的蛋白质功能片段与反-环
辛烯改性表面接触,从而在表面上固定蛋白质或功能蛋白质片段。通过该方法获得的在表面上固定蛋白质或功能蛋白质片段的表面,以及用于测量
配体与蛋白质或功能蛋白质片段结合的表面的方法。
