The invention discloses a separation matrix which comprises a plurality of separation ligands, defined by the formula R1-L1-N(R3)-L2-R, immobilized on a support, wherein R1 is a five- or six-membered, substituted or non-substituted ring structure or a hydroxyethyl or hydroxypropyl group; L1 is either a methylene group or a covalent bond; R2 is a five-or six-membered, substituted or non-substituted ring structure; L2 is either a methylene group or a covalent bond; R3 is a methyl group; and wherein if R1 is a hydroxyethyl group and L1 is a covalent bond, R2 is a substituted aromatic ring structure or a substituted or non-substituted aliphatic ring structure.
本发明公开了一种分离基质,它包括固定在支持物上的由式 R1-L1-N(R3)-
L2-R 定义的多个分离
配体,其中 R1 是五元或六元、取代或非取代的环结构或羟乙基或羟丙基;L1 是亚甲基或共价键;R2 是五元或六元、取代或非取代的环结构;
L2 是亚甲基或共价键;R3 是甲基;如果 R1 是羟乙基,L1 是共价键,则 R2 是取代的芳环结构或取代或非取代的脂环结构。
