| Abstract: | Our recent studies indicated that Rhodamine fibrosarcoma (RdF) tissue of rats accumulated large amounts of albumin and transferrin and that these proteins were essential for growth of RdF cells in primary cultures in serum-free medium. Therefore, the localizations of albumin and transferrin accumulated in RdF tissue were examined by immunohistochemical stainings. Both anti-rat albumin IgG and anti-rat transferrin IgG stained the cell surface of the tumor cells strongly, but the intracellular area only weakly. |
