【Abstract】 Objective To investigate the possibility of evaluating platelet adhesion and activation on biomaterials by detecting the CD62 antigen. Methods Platelet adhesion assay was carried out on polyethylene membranes, which were coated with Tris-HCl buffer, GST or GST-TFPI fusion protein. The number of platelet adhered on the membranes was counted by Scanning Electronic Microscope and the amount of CD62 was detected by immunoassay. Results The amount of CD62 was significantly correlated with the number of platelets adhered on the membrane. Conclusion CD62 antigen, which is present only on the irreversibly activated platelets, could be used as an important marker for evaluating the adhesion and activation of platelet on biomaterials.更多还原
