Provided is an adsorbent for separating and purifying useful proteins such as immunoglobulins. An adsorbent for protein separation / purification obtained by immobilizing a group represented by the general formula (1) on an insoluble carrier via a carbonyl group. (In the formula, Ar is a halogen atom, an alkyl group having 1 to 4 carbon atoms, a haloalkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms, an alkylsulfonyl group having 1 to 4 carbon atoms, a hydroxyl group, and cyano. Represents a phenyl group or a pyridyl group optionally substituted with a group selected from a group, a phenyl group, an acyl group having 1 to 5 carbon atoms and a nitro group, and X represents a single bond, a carbonyl group, a sulfonyl group, or Represents an alkylene group having 1 or 2 carbon atoms, n represents 1 or 2) [Selection figure] None |
