2614848-1	1989	Crystals of bovine antithrombin III were obtained in the presence of metal ions with ammonium sulphate as precipitating agent.	Ammonium Sulfate	85-102	serpin family C member 1	Homo sapiens	19-35	
6636046-1	1983	A hereditary abnormal antithrombin III (AT-III) "Antithrombin III Toyama" was purified from the plasma of a patient with recurrent thrombophlebitis by a procedure involving barium chloride and ammonium sulfate fractionations, affinity chromatography on anti-AT-III-Sepharose gel, and DEAE-Sephadex chromatography.	Ammonium Sulfate	193-209	serpin family C member 1	Homo sapiens	40-46
