Ristocetin 120-130 neuraminidase 1 Homo sapiens 48-61 6239876-8 1984 A similar decrease in ristocetin cofactor activity was seen if von Willebrand factor was treated only with neuraminidase and beta-galactosidase. Ristocetin 22-32 neuraminidase 1 Homo sapiens 107-120 30849118-10 2019 In contrast, induction of binding of VWF to glycoprotein 1b on platelets using the VWF-activating protein ristocetin resulted in the removal of platelet sialic acid by translocation of platelet neuraminidase to the platelet surface. Ristocetin 106-116 neuraminidase 1 Homo sapiens 194-207
