[Platelet membrane glycoprotein V and clinical significance of plasma GPVf 1 level].
Thrombin hydrolyzes platelet membrane glycoprotein V (GPV) which has leucine rich repetitive modules specifically, and releases GPVf1 (fragment of N terminal in GPV). The GPV related antigen level in plasma will thus reflect activation of platelet in vivo. The ELISA assay to measure the concentration of GPV and GPVf1 in plasma using polyclonal anti-GPV antibody, was established. The concentration of GPV and GPVf1 in plasma by using polyclonal anti-GPV antibody was established. The concentration of GPV related antigen in plasma is significantly higher in patients with thrombosis and correlated well with thrombotic episodes. It was suggested that the measurement of plasma-GPV-related antigen level is a useful marker for the diagnosis of thrombosis or prethrombotic states.
