10451222-5	1999	This hCG isoform was not only 100% nicked, but also contained 100% tetrasaccharide-core O-linked carbohydrate moieties in its beta COOH-terminal region.	tetrasaccharide	67-82	chorionic gonadotropin subunit beta 5	Homo sapiens	5-8	
16033104-9	2005	RESULTS: We found that hCG isolated from serum, amniotic fluid and supernatant of the cell line Jeg3 were strong inhibitors with at least 10(3)-fold higher potency compared to the monovalent tetrasaccharide sialyl Lewisx.	tetrasaccharide	191-206	chorionic gonadotropin subunit beta 5	Homo sapiens	23-26	
3335536-4	1988	In the case of normal hCG and hydatidiform mole hCG, oligosaccharides containing the tetrasaccharide core occupy approximately 10% of the total mucin-type sugar chains.	tetrasaccharide	85-100	chorionic gonadotropin subunit beta 5	Homo sapiens	48-51	
3335536-5	1988	The ratio of the tetrasaccharide containing oligosaccharides is increased prominently to approximately 60% in choriocarcinoma hCG.	tetrasaccharide	17-32	chorionic gonadotropin subunit beta 5	Homo sapiens	126-129
