among the lectins tested , only aba-i was found to bind to a sialylated glycopeptide , whic which was prepared from human erythrocyte glycophorin a and contains three three tetrasaccharide chains having the structure of alpha-neuac- ( 2 -- -- 3 ) -beta-d-galp- ( 1 -- -- 3 ) -neuac- ( 2 -- -- 6 ) ] -alpha-d-galp nac- ( 1 -- -- , with an association constant of 15 microm , whereas the association constants of the other four lectins for this sialylated glycopeptide were less than 3.5 mm .
