Abstract
Antibody is removed from the blood of patients who are being treated or diagnosed with exogenous macromolecules, such as immunotoxins. As the immunotoxins are foreign antigens, the patient will develop an immune response. The antibodies produced by the immune response upon subsequent immunization with the immunotoxins will interfere with the desired function of the immunotoxins by preventing them from binding with their specific target site. By extracorporeally removing the antibodies, the activity of the immunotoxins can be enhanced.
