24234228-5	1982	The slight differences observed when fumarase is immobilized at concentrations higher than 50 [Symbol: see text]g/g gel must be attributed to diffusional limitation at the surface of the Sepharose matrix.	Sepharose	187-196	fumarate hydratase	Sus scrofa	37-45	
6830817-11	1983	Moreover, it is shown that only fumarase tetramers with all four subunits nitrated are unable to bind to a Sepharose-pyromellitic acid affinity column.	Sepharose	107-116	fumarate hydratase	Sus scrofa	32-40
