Abstract

The invention aims at providing an adsorbent for bacterial toxins, a method for removal of such toxins by adsorption, and an adsorber packed with said adsorbent. Provided are an adsorbent for bacterial toxins, which comprises a water-insoluble porous material having a mode of pore radius of 20 angstroms to 1,000 angstroms, a method for removal of bacterial toxins using said adsorbent, and an adsorber packed with said adsorbent.

Claims (3)

1. The method for removal of exotoxin by adsorption, which comprises the step of contacting an adsorbent with a bacterial toxin-containing fluid, wherein the adsorbent comprises a water-insoluble porous material having a mode of pore radius of 100 angstroms to 600 angstroms, and wherein the water-insoluble porous material comprises a polystyrene-based material,

wherein the exotoxin is selected from the group consisting of Toxic shock syndrome toxin-1, staphylococcal enterotoxin B, staphylococcal enterotoxin Cl, staphylococcal enterotoxin D, and staphylococcal enterotoxin E,

wherein the polystyrene-based material does not have a side chain or ligand.
