Assembly and GPIIIa Content of Cytoskeletal Core in Platelets Agglutinated With Bovine von Willebrand Factor
The association between occupancy of the von Willebrand factor (vWf) receptor glycoprotein (GP) Ib, agglutination, and the assembly and composition of the cytoskeletal core was studied in ‘261-surface-labeled aspirin-treated washed platelets. Binding of ligands to GPllb-llla and platelet aggregation were abolished by addition of EDTA. Platelet agglutination induced by bovine vWf generated a com...
متن کاملAssembly and GPIIIa content of cytoskeletal core in platelets agglutinated with bovine von Willebrand factor.
The association between occupancy of the von Willebrand factor (vWf) receptor glycoprotein (GP) Ib, agglutination, and the assembly and composition of the cytoskeletal core was studied in 125I-surface-labeled aspirin-treated washed platelets. Binding of ligands to GPIIb-IIIa and platelet aggregation were abolished by addition of EDTA. Platelet agglutination induced by bovine vWf generated a com...
متن کاملUnique interactions of asialo von Willebrand factor with platelets in platelet-type von Willebrand disease.
The present studies demonstrate that platelets from patients with platelet-type von Willebrand disease show specific and saturable binding of asialo von Willebrand factor (AS-vWF) under conditions where such binding is not observed with normal platelets. Although specific binding of 125I-AS-vWF to formalin-fixed normal platelets could not be demonstrated, specific binding to fixed patient plate...
متن کاملA collagen-binding glycoprotein from bovine platelets is identical to propolypeptide of von Willebrand factor.
Several proteins from bovine platelet lysate bound to type I collagen immobilized to the beads of formyl derivatives of cellulose. Among these proteins, a protein of about 100,000 daltons was purified to homogeneity by two additional affinity chromatographies, an organomercurial-agarose and a lentil lectin-agarose. This protein consisted of a single polypeptide chain which contains carbohydrate...
متن کاملOrganization of von Willebrand factor on surface-activated platelets.
The distribution and organization of von Willebrand factor (vWF) multimers on platelets after surface activation have not been fully characterized. In the present study, washed human platelets were allowed to interact with Formvar-coated, electron microscope grids for 20 minutes at 37 degrees C and then fixed. After fixation, cells were washed and then incubated with buffer alone, human plasma,...
