Ristocetin A sulfate

Description

Ristocetin A is an antibiotic that is used to staphylococcal infections. However, side effects of ristocetin A included thrombocytopenia and platelet agglutination. Ristocetin A is now used in two assays related to these actions, the ristocetin cofactor assay and the ristocetin-induced platelet aggregation assay. Both assays are used in the diagnosis of von Willebrand disease and other bleeding disorders.
