1652125-1	1991	The accumulation of fluorescein (FITC)-labelled bovine albumin was measured against the extracellular-fluid-phase marker FITC-inulin within confluent monolayers of the opossum kidney cell line OK. Fluorescence and electron microscopic pictures show that FITC-albumin is taken up by endocytosis and appears in a vesicular intracellular distribution.	Fluorescein	20-31	albumin	Bos taurus	55-62
