1009925-1	1976	The major C4 component of human serum cholinesterase was highly purified by a two-step procedure involving chromatography on DEAE-cellulose and preparative disc electrophoresis.	DEAE-Cellulose	125-139	butyrylcholinesterase	Homo sapiens	38-52	
5441375-1	1970	Cholinesterase was purified from human serum by a three-stage procedure involving chromatography on DEAE-cellulose at pH4.0, an electrofocusing technique and gel filtration on Sephadex G-200.	DEAE-Cellulose	100-114	butyrylcholinesterase	Homo sapiens	0-14	
30364910-12	2015	CONCLUSIONS: Separation of proteins and particularly of BuChE on a chromatographic DEAE Cellulose column can be considered as a method for separation and purification of BuChE from human plasma.	DEAE-Cellulose	83-97	butyrylcholinesterase	Homo sapiens	56-61
