Two‐dimensional immunoelectrophoretic techniques were used to elucidate the origin of a dominant beer antigen 1. Immunochemical identity was found between a protein Z associated with β‐amylase in extracts of barley and one form of the beer antigen 1a. Immunochemical identity was also found between a papain‐modified form of protein Z and the antigen form 1b from beer. The results indicate that protein Z is very resistant to degradation and denaturation during malting and brewing.
