Abstract:
Provided is an accelerated method for preparing platelet rich plasma (PrP) without centrifugation or filtration. The method comprises contacting a sample of whole blood with an anti-coagulant and an inducer of Rouleaux formation; allowing the mixture to stand thereby depleting the sample of RBCs, and collecting the platelet-rich plasma fraction. The PrP volume obtained by the present method is about 10-60% of the volume of the starting whole blood sample, and contains less than 200,000 RBCs and at least 100,000 platelets per microliter.

Claim (Index 9):
A method for preparing platelet rich plasma comprising:\n a) exposing a sample of whole blood to an anti-coagulant and an inducer of Rouleaux formation, wherein a portion of the inducer of Rouleaux is conjugated to magnetic beads and another portion is present as unconjugated; b) subjecting the mixture from a) to a magnetic field such that red blood cells to settle to the bottom; c) removing the plasma fraction from the top, wherein no centrifugation step is used, and wherein the plasma fraction contains at least 100,000 platelets and less than 100,000 red blood cells per microliter.
