  • Publication number: 20050063935
    Abstract: The present invention provides an adsorbent for efficiently adsorbing and removing cytokine in liquid and a method for removing cytokine in liquid by the adsorbent. Also, the present invention provides an adsorber for removing cytokine in liquid. Specifically, an adsorbent for cytokine is obtained by immobilizing a compound having a log P value of at least 2.50 (P is the partition coefficient in an octanol-water system) on a water-insoluble carrier. By contacting a liquid containing cytokine with the adsorbent for cytokine, the cytokine in the liquid can be effectively adsorbed and removed. Furthermore, cytokine can be efficiently adsorbed and removed by an adsorber comprising a container having an inlet and an outlet for liquid and a means for preventing the adsorbent from flowing out of the container, which is filled with the adsorbent.
