Adsorbent for peptidoglycan and method and apparatus for adsorptively removing peptidoglycan
An adsorbent for peptidoglycan which comprises an water-insoluble porous material having an amino group and having a molecular weight of exclusion limit of at least 50,000, and a method for removing peptidoglycan by adsorption, which comprises a step of contacting the adsorbent to a liquid containing peptidoglycan.
1. A method for removing peptidoglycan, which comprises bringing blood containing peptidoglycan into contact with an adsorbent for peptidoglycan comprising a water-insoluble porous material consisting essentially of an organic material selected from the group consisting of a synthetic polymer and a polysaccharide, wherein an amino group is attached to said water-insoluble porous material with covalent bond, and having a molecular weight of exclusion limit of at least 50,000 and thereby removing peptidoglycan from said blood, wherein after peptidoglycan is removed from the blood, the treated blood, containing a reduced amount of peptidoglycan, is returned to the body in an extracorporeal circulation system.
