| description | To provide a novel packing material for liquid chromatography capable of separating and purifying, or collecting and recovering, a biopolymer such as a protein or a peptide by adsorption and desorption by a pH change without being influenced by the isoelectric point of the protein or by the salt concentration in a solvent in which the biopolymer such as the protein is dissolved, and to provide a process for concentrating and recovering a desired biopolymer such as a protein or a peptide from a large amount of dilute cell culture solution by means of such a packing material. Separation and purification, or collection and recovery, of a biopolymer, is carried out by liquid chromatography by means of a packing material for liquid chromatography comprising a base matrix and a ligand immobilized to the base matrix, wherein the base matrix is a hydrophilic base matrix having alcoholic hydroxy groups on its surface, the ligand is at least one ligand selected from the group consisting of an ±-amino acid represented by the following formula (1):
RCH(NH 2 )COOH(1)
wherein R is an aromatic group or a C 5-7 non-ionic aliphatic group, and an aminomethyl benzoic acid, and the ligand is immobilized to the base matrix by an amide bond or an urethane bond via the amino group contained in the compound represented by the formula (1). |
