Title:
CELL CRYOPRESERVATION HOLLOW FIBER MEMBRANE
Document Type and Number:
WIPO Patent Application WO/2022/092067
Kind Code:
A1
Abstract:
A hollow fiber membrane that is made from a cellulose ester and is for cell cryopreservation, wherein a decrease in strength when used for cryopreservation of a cell is inhibited. A cell cryopreservation hollow fiber membrane that contains a cellulose ester, wherein the breaking strength of the membrane when thawed after being frozen by means of the vitrification method is at least 80% of the breaking strength of the membrane when moist before freezing.
