CHROMATOGRAPHY LIGAND

摘要

The present invention relates to a chromatography ligand defined by the following formula (I) R₁-R₂-N(R₃)-R₄-R₅ wherein R₁ is a substituted or non-substituted phenyl group; R₂ is a hydrocarbon chain comprising 0-4 carbon atoms; R₃ is a hydrocarbon chain comprising 1-3 carbon atoms; R₄ is a hydrocarbon chain comprising 1-5 carbon atoms; and R₅ 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.
