Abstract: The present invention relates to a process for treating blood. The process involves separating the blood into plasma and cellular components. The plasma component is passed through a column containing a polyimide particulate carrier. The polyimide carrier contains immobilized proteins, such as protein A, bonded to its surface. The polyimide carrier can be used for removing or modifying a biochemically active substance in the blood plasma.
