Abstract
The serum-protein and -lipoprotein patterns of rats, given a purified diet containing 0 percent, 0- 005 percent or 0- 03 percent 2-acetamido-fluorene, have been determined by disk electrophoresis. An abnormal high-density lipoprotein was detected from the first week of the experiment in the serum of the animals given the carcinogen. The low-density lipoproteins also increased on prolonged feeding with the carcinogen.
