It has been demonstrated in preliminary experiments that two strains of rat tumor cells (WRC-256 and TSAT-72) utilize alpha-2-globulin more selectively than other protein components of human serum. Cells of strain TSAT-72 show some utilization of beta-globulins also. Separate experiments demonstrated the utilization of glycoproteins by both strains.
