PROBLEM:  Inhibition of platelet aggregation was also observed with the N - terminal fragment of lactotransferrin ( residues 3 - 281 ; 50 % inhibition = 2 microM ) and with CFQWQRNMRKVRGPPVSC synthetic octodecapeptide ( residues 20 - 37 ; 50 % inhibition = 20 microM ) corresponding to one of the two external loops ( residues 28 - 34 and 39 - 42 ) where we recently located the receptor - binding site .

SOLUTION: fragment
