Abstract
A substance possessing physiological activity is coupled to a styrene-glycidyl methacrylate polymer through a spacer, and is used to isolate from a mixture a substance that can adhere to the substance possessing physiological activity. Preferably the polymer is in the form of a microsphere, the substance possessing physiological activity is 3-[(5-(2,3-dimethoxy-6-methyl-1,4-benzoquinonyl)]-2-nonyl-2-propionic acid or derivative thereof, and the spacer is an ethylene glycol diglycidyl ether derivative. The mixture may be a cell extract and the substance isolated a protein that is a receptor to the substance possessing physiological activity.
