Abstract
A method is disclosed for removal of cryoprotectants from preserved suspension of biological cells and tissues. Sorbent materials are used, alone or in combination, to bind the cryoprotectant component of preserved cell suspensions with minimal osmotic stress on the preserved cells. The present method is used to effectively remove the cryoprotectants from cryopreserved cells and tissues prior to their use in transfusion, transplantation, insemination or other applications, with minimal osmotic damage due to cell swelling. Specific devices and methods are described.
