  • Endotoxin detoxifying material
    Patent number: 4771104
    Abstract: The present invention provides (1) an endotoxin detoxifying material comprising a fibrous carrier to which Polymyxin is fixed, (2) an endotoxin detoxifying material comprising a carrier to which Polymyxin and a basic nitrogen atom are fixed, and (3) a method of removing endotoxin from a fluid by contacting the fluid with the endotoxin detoxifying material comprising a carrier to which Polymyxin is fixed.The present invention makes it possible to contact blood with Polymixin directly and safely and gives a new method of therapy endotoxemia or prophylaxis of endotoxemia.
