Absorbent and column for extracorporeal circulation

摘要

The present invention provides an absorbent which can remove cells present in blood including activated leukocytes such as granulocytes and monocytes, and cancer cells as well as can remove cytokines which facilitate the activation of the remaining cells, and further has no concern for pressure loss and has high configuration stability. That is, the present invention provides an absorbent which absorbs the granulocytes and the monocytes in blood, an absorbent for cancer therapy which absorbs an immunosuppressive protein and an absorbent having a bilayer structure of a net and a nonwoven fabric, having a zeta potential of -20 mV or more, as well as a blood circulation column containing any of the absorbents filled therein.
