FILTER HAVING OPTIMIZED EXTERNAL SHAPE OF RIDGES INSIDE FILTER

摘要

A filter having a container filled with a cell separation material. The filter comprises a fluid introduction port in either an upper section or lower section of the container and a fluid discharge port on the opposite side thereto. The filter has ridges on the surface of the filled cell separation material, that protrude towards either the fluid introduction port side or the fluid discharge port side. The height (y) and the length (x) of the ridges fulfil formula (1) y = -ax² + bx and/or formula (2) y = ax² - bx. The ratio (a/b) between a and b is adjusted to within the range 0.03-0.25. The purpose of the present invention is to provide a cell separation filter having improved cell recovery efficiency and a cell separation method that uses the cell separation filter and whereby target cells can be efficiently recovered.
