PURPOSE:To provide a separating agent suitable for the separation of optical isomers, by preparing a poly-alpha-amino acid having a polymerization degree of within a specific range and derived from monomers such as alanine, valine, etc., and supporting the amino acid to a carrier such as a porous organic carrier. CONSTITUTION:A poly-alpha-amino acid having a polymerization degree of 2- 1,000,000, preferably 4-100,000 (e.g. a polymer derived from the monomers such as leucine, isoleucine, threonine, serine, methionine, phenylalanine, glutamic acid, their ether, ester, amide, urethane, etc.) is supported on a carrier, preferably a porous organic carrier such as polystyrene, polyacrylamide, polyacrylate, etc. The separation agent is preferably used especially in a liquid chromatography or thin-layer chromatography.
