title: Pinocytosis of fluorescein-labelled growth-promoting alpha-globulin in human diploid cells.
abstract: Fluorescein isothiocyanate conjugated growth-promoting alpha-globulin (FITC-GPAG) binds to human diploid cells LEP 19 at 37 degrees C. After the initial binding step, labelled GPAG is progressively internalized by the cells. FITC-GPAG is present in pinocytic vesicles localized in the perinuclear region of the cells and its pinocytosis occurs without cell surface redistribution of GPAG.
