title: Internalization and transport of mouse beta-interferon into the cell nucleus.
abstract: An electron microscopic technique employing postembedding immunolabeling was used to identify unmodified, intracellular MuIFN-beta molecules. The MuIFN-beta was rapidly internalized by receptor-dependent endocytosis and within three minutes a majority of internalized MuIFN-beta molecules was detected within the cell nucleus.
