Abstract
Transferrin was localized in 48-hr cultured adult rat hepatocytes by indirect immunoperoxidase following paraformaldehyde--glutaraldehyde fixation and the use of saponin as a membrane permeabilizing agent. The protein, present in all the parenchymal cells in variable amounts, was found to be specifically located in the endoplasmic reticulum and Golgi apparatus. These results are consistent with recent reports claiming that all adult hepatocytes may synthesize a given liver plasma protein at a given time. The procedure used in this study should be particularly useful for the detection of intracellular antigens in various intact cell types.
