The mechanism of biliary excretion of α1‐acid glycoprotein in the rat: Evidence for a molecular weight‐dependent, nonreceptor‐mediated pathway
Peter Thomas, Carol A. Toth, Norman Zamcheck – 1 November 1982 – The transport of human α1‐acid glycoprotein from the circulation to the bile has been studied in the rat. Biliary excretion was proportional to the i.v. injected dose, and the percentage excreted remained constant. The amount excreted in the bile (over 4 hr) was inversely related to the rate of hepatic (hepatocyte) uptake and the galactose receptor which is specific for asialo glycoproteins was not involved.
