A preparation of duodenal alkaline phosphatase from 11-day-old mice contains an enzymatically inactive material that cross reacts with antiserum prepared against one isozyme of 20-day alkaline phosphatase. After precipitation of this material from solution, the antiserum cannot precipitate the 20-day enzyme
