PHOSPHORYLCHOLINE GROUP-CONTAINING COMPOUND AND PHOSPHORYLCHOLINE COMPLEX

摘要

[Problem] To provide: a phosphorylcholine group-containing compound which is easily manufactured and with which a phosphorylcholine complex suitable for use as a phosphorylcholine antigen can be produced; and the phosphorylcholine complex. [Solution] The present invention is: a phosphorylcholine group-containing compound having a structure represented by formula (1); and a phosphorylcholine-protein complex having a structure in which the phosphorylcholine group-containing compound and an amino acid amine site of a protein are amide bonded. (X is a hydrogen atom or a monovalent cation residue, or a hydroxysuccinimide group.)
