US 2020/0048597 A1 · SEPARATION SUBSTRATE, CELL SEPARATION FILTER, AND METHOD FOR PRODUCING PLATELET

Abstract

An object of the present invention is to provide a separation substrate having a high megakaryocyte blocking rate and a high platelet permeation rate, and a cell separation filter and a method for producing a platelet which use the same. The separation substrate of the present invention is a separation substrate including non-woven fabric for separating a platelet from a cell suspension containing a megakaryocyte and the platelet, in which an average pore diameter of the separation substrate is 2.0 μm to 15.0 μm, and a thickness of the separation substrate is 10 μm to 500 μm.
