204321-1	1978	The use of perchloric acid and water for the extraction of CEA from tumour and foetal tissues has been investigated.	Perchloric Acid	11-26	CEA cell adhesion molecule 3	Homo sapiens	59-62	
204321-1	1978	The use of perchloric acid and water for the extraction of CEA from tumour and foetal tissues has been investigated.	Water	31-36	CEA cell adhesion molecule 3	Homo sapiens	59-62	
204321-2	1978	In the case of tumour, lower recoveries of CEA were obtained from perchloric acid extracts than from aqueous extracts of the same tissue.	Perchloric Acid	66-81	CEA cell adhesion molecule 3	Homo sapiens	43-46	
204321-3	1978	CEA has also been extracted with 3M KCl solution from insoluble perchloric acid residues of tumour homogenates and cancer patients" serum.	Potassium Chloride	36-39	CEA cell adhesion molecule 3	Homo sapiens	0-3	
204321-3	1978	CEA has also been extracted with 3M KCl solution from insoluble perchloric acid residues of tumour homogenates and cancer patients" serum.	Perchloric Acid	64-79	CEA cell adhesion molecule 3	Homo sapiens	0-3	
204321-4	1978	Whilst a large proportion of CEA activity recovered from tumour was associated with the perchloric acid residue, the corresponding amounts from serum were very small.	Perchloric Acid	88-103	CEA cell adhesion molecule 3	Homo sapiens	29-32	
204321-5	1978	CEA elution volumes for each extract, obtained by assay of Sephadex G-200 column fractions, showed significant heterogeneity in molecular size.	sephadex	59-67	CEA cell adhesion molecule 3	Homo sapiens	0-3	
204321-6	1978	The purified CEA pools also showed quantitative variations in the binding profiles on Con A-Sepharose.	Sepharose	92-101	CEA cell adhesion molecule 3	Homo sapiens	13-16	
204321-7	1978	It has been shown that perchloric acid modifies the carbohydrate in CEA, thus altering its Con A-binding properties.	Perchloric Acid	23-38	CEA cell adhesion molecule 3	Homo sapiens	68-71	
204321-7	1978	It has been shown that perchloric acid modifies the carbohydrate in CEA, thus altering its Con A-binding properties.	Carbohydrates	52-64	CEA cell adhesion molecule 3	Homo sapiens	68-71
