title: Demonstration of the simultaneous presence of transferrin, hemopexin and albumin in the same adult rat hepatocyte.
abstract: The location of three plasma proteins (transferrin, hemopexin, and albumin) in hepatocytes was investigated in adult rats. The synthesis of transferrin anf hemopexin has been established by ultrastructural studies showing a labeling of the rough endoplasmic reticulum (RER). By using an indirect immunoenzymatic method with monospecific antibody solutions, the three proteins were detected in the same hepatocyte. The simultaneous presence of different plasma proteins in hepatocytes seems to point to the fact that the synthesis in these cells could be a non-specialized type.
