An embodiment of the present invention provides an improved method for identifying the epitope of a protein, said method comprising the following steps: (A) a step in which cells that have been differentiated from stem cells or precursor cells derived therefrom, and that express major histocompatibility complex (MHC molecules), are brought into contact with a target protein; (B) a step in which a complex of MHC molecules and peptides contained in the target protein is isolated from the cells that express MHC molecules; and (C) a step in which the peptides are eluted from the complex and identified. |
