Carbohydrate recognition of anti-Tn antibodies by competitive assay¹.

Carbohydrate Inhibitor (%)	6 (mM)	3 (mM)	1,5 (mM)	0,75 (mM)
GalNAcαBzl	32	33	31	5
Glc	4	2	1	2

¹Competitive assay using carbohydrates as inhibitors of anti-OSM antibody recognition. Different concentrations of carbohydrates preincubated with anti-OSM antibodies showed the significance of sugar residue in the antigen recognition. GalNAcαBzl, structure related to Tn-antigen, is important inhibitor of antibody interaction whereas glucose (Glc) has not effect (control).
