    • This invention provides a method for immobilizing proteins comprising: step 1 of purifying target proteins to be immobilized, which have a first tag portion and a second tag portion, with the use of the first tag portion; step 2 of activating reactive groups capable of covalently binding to the proteins on a carrier for immobilization; and step 3 of allowing a solution containing the proteins purified in step 1 to react with the carrier after step 2, wherein, in step 3, the proteins are immobilized on the carrier via interactions between the second tag portion and the site of the carrier to which the second tag portion binds and via covalent binding between the reactive groups and the proteins. This method enables the stable immobilization of various types of target proteins on a carrier regardless of the amounts of target proteins and without nonspecific immobilization of contaminating proteins.
    • 本发明提供了一种固定蛋白质的方法,包括:使用第一标签部分纯化具有第一标签部分和第二标签部分的待固定的靶蛋白质的步骤1; 启动能够共价结合载体上的蛋白质以进行固定的反应性基团的步骤2; 和步骤3,使步骤2中纯化的蛋白质溶液与载体反应,其中在步骤3中,蛋白质通过第二标签部分和载体位点之间的相互作用固定在载体上, 其中第二标签部分结合并且通过反应性基团和蛋白质之间的共价结合。 这种方法可以使各种类型的靶蛋白稳定地固定在载体上,而不管靶蛋白的量如何,并且不污染蛋白质的非特异性固定。
