A 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. 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 alpha-amino acid which is immobilized to the base matrix by an amide bond or an urethane bond via the amino group contained in the alpha-amino acid.
