The present invention relates to an IgG-binding compound, which more specifically has affinity for human IgGs of κ-type and functional derivatives thereof. More specifically, the compound according to the invention comprises an N,N-alkylated urea moiety located between an aromatic part and another part, which is a linear or cyclic substituted or unsubstituted aliphatic group. The compound binds to a pocket-shaped binding site present on all human IgG κ-Fabs, which site is located between the two domains (CH1 and CL) of its constant part. Accordingly, the compound according to the invention is a ligand for human IgGs of κ-type, and consequently, the invention also relates to a separation matrix for affinity chromatography, which matrix comprises said compound, as well as to other uses of the compound.
本发明涉及一种IgG结合化合物,更具体地具有对人类κ型IgG及其功能衍
生物的亲和力。更具体地,根据本发明,该化合物包括位于芳香部分和另一部分之间的N,N-烷基化
脲基团,该另一部分是线性或环状取代或未取代的脂肪族基团。该化合物结合到所有人类IgG κ-Fab上存在的口袋状结合位点,该位点位于其恒定部分的两个域(CH1和CL)之间。因此,根据本发明,该化合物是人类κ型IgG的
配体,因此,本发明还涉及一种亲和层析的分离基质,该基质包括所述化合物,以及该化合物的其他用途。
