[Marker proteins of the differentiation of cultured human prostatic epithelial cells]

The typical differences in the protein spectrum of cultured epithelial cells of the human definitive prostate and its premordium were revealed by the electrophoresis and electrofocusing procedure. Marker proteins typical of the cultured prostate epithelial cells, which underwent differentiation, have molecular weight of 70000-74000 Dalton and their isoelectric points are 6.6; 7; 7.5.
