Title:
COMPOSITION AND METHOD FOR RAPID SEPARATION OF WHOLE BLOOD
Document Type and Number:
WIPO Patent Application WO/2022/166230
Kind Code:
A1
Abstract:
Disclosed are a composition and method for rapid separation of whole blood. The composition comprises a high-density particulate matter and a high-molecular polymer-specific biological macromolecule polymer. The main mechanism of the present invention is that the specific biological macromolecules on the high-molecular polymer bind to red blood cells and white blood cells in a whole blood sample to form an aggregate, and in addition, high-density particulate matters form a new complex polymer again by means of adsorption or the specific biological macromolecules on the surface of the high-density particulate matters binding to the red blood cells and the white blood cells on the aggregates. The polymer is acceleratory precipitated under the action of an external force, thereby achieving the separation of red blood cells and white blood cells in the whole blood samples from serum or plasma.
