Part Description

LP207921-0   Platelet aggregation.ristocetin inhibitor
Ristocetin is an antibiotic, obtained from Nocardia lurida, previously used to treat staphylococcal infections. It is no longer used clinically because of its toxicity. It causes platelet agglutination and blood coagulation and is used to assay those functions in vitro, e.g. to diagnose von Willebrand disease or the Bernard-Soulier syndrome. Platelet agglutination caused by ristocetin can occur only in the presence of von Willebrand factor, so if ristocetin is added to blood lacking the factor, it will not coagulate. Ristocetin is also antibacterial. Copyright Text is available under the Creative Commons Attribution/Share-Alike License. See http://creativecommons.org/licenses/by-sa/3.0/ for details.
