Chromatography ligand
View Patent ↗The present invention relates to a chromatography ligand defined by the following formula (I) R 1 —R 2 —N(R 3 )—R 4 —R 5 wherein R 1 is a substituted or non-substituted phenyl group; R 2 is a hydrocarbon chain comprising 0-4 carbon atoms; R 3 is a hydrocarbon chain comprising 1-3 carbon atoms; R 4 is a hydrocarbon chain comprising 1-5 carbon atoms; and R 5 is OH or H. The invention also comprises a separation matrix, comprising the described ligands coupled to a porous support, such as particles or a membrane. The ligand and matrix according to the invention is useful for purification of biomolecules or organic compounds, such as proteins, polypeptides, DNA etc. An advantageous use according to the invention is the purification of antibodies.
1. A separation matrix comprising N-benzyl-N-methyl ethanol amine ligands coupled to a support, wherein said support is linked to nitrogen atom of the ligand through a linker.
