RESUMO
The mechanism by which ristocetin induces platelet agglutination in the presence of the von Willebrand factor was studied by chemically altering ristocetin and a similar antibiotic, vancomycin, by reaction with a water-soluble carbodiimide in the presence of glycine methyl ester at pH 4.75. Altering ristocetin's phenolic groups (which are thought to be important in its peptide-binding properties) resulted in a loss of both platelet-agglutinating and antibiotic activities. Restoring the phenolic groups with hydroxylamine restored both activities.
