THE SOURCE 12 CELL LINE OF ORIGIN WAS S49.1, OBTAINED FROM THE SALK INSTITUTE CELL SOURCE 13 CULTURE CENTER IN 1974. THE ODC- AMPLIFIED LYMPHOMA CELL LINE SOURCE 14 OBTAINED AS A RESULT OF SELECTION WITH DFMO WAS D4. THE GENE HAS SOURCE 15 BEEN CLONED FROM MANY MOUSE STRAINS SINCE, AND THE ORF IS INVARIANT SOURCE 16 AMONG THESE, SO FAR AS WE KNOW. THE EXPRESSION OF THE PROTEIN WAS IN SOURCE 17 E.COLI.
