15. A process of preparing an adsorbent for removing low and/or very low density lipoprotein from body fluid in extracorporeal circulation treatment comprising a water-insoluble porous hard gel with exclusion limit of 106 to 109 daltons on which a sulfated compound is immobilized, wherein said water-insoluble porous hard gel is reacted with epichlorhydrin or a polyoxirane compound to introduce epoxy groups on to the gel, and then the resulting epoxy-activated gel is reacted with the sulfated compound;
- said sulfated compound being a compound obtained by sulfation of a hydroxy-containing compound.
