Abstract
Coagulation and optical (based on chromogenic substrate) methods were employed to examine antithrombin activity of erythrocytes and erythrocyte-derived microvesicles isolated days 7, 14, 21, and 28 on erythrocyte storage. The erythrocyte-derived microvesicles decelerated fibrin clot formation from fibrinogen in the presence of exogenous thrombin both with and without heparin. Microvesicles reduced optical density of chromogenic substrate. These data suggest that erythrocyte-derived microvesicles display a prominent antithrombin activity, which significantly increases during erythrocyte storage.
