total plasma proteins and serum albumin were taken up by a mechanism of fluid endocytosis with low clearance ( 0.1 microliter [ mg cell protein ] -1 h-1 ) , while low-density lipoprotein ( ldl ) and transferrin were taken up by a receptor-mediated process with a clearance of two to three orders of magnitude higher than that of serum albumin .
