Zusammenfassung:PROBLEM TO BE SOLVED: To provide an antigen-binding protein capable of binding to mammalian IgG.SOLUTION: The antigen-binding protein of the invention has a framework region preferably corresponding to that of an antibody naturally lacking the light chain as found in camelids. Further, the invention relates to a nucleic acid encoding such an antigen-binding protein, an immunoabsorbent including such a protein, and use of such an immunoabsorbent for purification of mammalian IgG antibodies, and for therapeutic apheresis. 【課題】哺乳動物IgGと結合できる抗原結合タンパク質の提供。【解決手段】抗原結合タンパク質のフレームワーク領域は、ラクダ科動物において見ることができるような、天然に軽鎖を欠く抗体の領域に対応することが好ましい。さらに、このような抗原結合タンパク質をコードする核酸、このようなタンパク質を含む免疫吸着物質、哺乳動物IgG抗体の精製のため、及び治療的アフェレーシスのためのこのような免疫吸着物質の使用に関する。【選択図】なし
