Time-dependent association between platelet-bound fibrinogen and the Triton X-100 insoluble cytoskeleton.
Previous studies indicated a correlation between the formation of EDTA-resistant (irreversible) platelet-fibrinogen interactions and platelet cytoskeleton formation. The present study explored the direct association of membrane-bound fibrinogen with the Triton X-100 (Sigma Chemical Co, St Louis, MO) insoluble cytoskeleton of aspirin-treated, gel-filtered platelets, activated but not aggregated ...
متن کاملThe Triton X-100-insoluble residue ("cytoskeleton") of aggregated platelets contains increased lipid phosphorus as well as 125I-labeled glycoproteins.
When ‘25l-labeled blood platelets were lysed with an equal volume of 2% Triton X-100, 10 mM EGTA, and 100 mM Tris, pH 7.4. the Triton-insoluble residue (“cytoskeleton”) contained about 1 1 % of the platelet protein. predominantly actin and actin-binding protein, 3.5% of the platelet radioactivity, and less than 2% of the platelet lipid phosphorus. Radioautographs of polyacrylamide gels of this ...

متن کاملIdentification of membrane proteins mediating the interaction of human platelets
Membrane glycoproteins that mediate platelet-platelet interactions were investigated by identifying those associated with the cytoskeletal structures from aggregated platelets. The cytoskeletal structures from washed platelets, thrombin-activated platelets (platelets incubated with thrombin in the presence of mM EDTA to prevent aggregation) and thrombin- aggregated platelets (platelets activate...
متن کاملThe effect of glycoprotein IIb-IIIa receptor occupancy on the cytoskeleton of resting and activated platelets.
The platelet integrin, glycoprotein IIb-IIIa (GPIIb-IIIa), serves as the receptor for fibrinogen. This study examined what effect GPIIb-IIIa receptor occupancy had on the cytoskeleton of resting and activated platelets. Triton X-100-insoluble residues (cytoskeletons) were isolated from resting washed platelets incubated with either 500 microM RGDS or 500 microM RGES and examined for protein con...
