Title (EN) USE OF A FILTER FOR DEFROSTING CELLS
(FR) UTILISATION D'UN FILTRE POUR DECONGELER DES CELLULES
Abstract:
(EN) The invention relates to a method for cell defrosting, comprising a step of defrosting a cell suspension consisting of a freezing medium and of cells, followed by a step of removing said freezing medium by filtration, said step of removing the freezing medium being carried out without the previous or simultaneous supply of medium. In particular, the filter is hydrophobic or, before addition of the cell suspension to be frozen, has been covered with a hydrophobic liquid forming a temporary barrier between the filter and the cell suspension. During defrosting, said hydrophobic liquid is removed by the application of a driving force which makes the liquid pass through the filter.
(FR) Procédé de décongélation cellulaire, comprenant une étape de décongélation d'une suspension cellulaire constituée d'un milieu de congélation et de cellules, suivie d'une étape d'élimination dudit milieu de congélation par filtration, ladite étape d'élimination du milieu de congélation étant effectuée sans apport préalable ou simultané de milieu. En particulier, le filtre est hydrophobe, ou a été recouvert, avant l'ajout de la suspension cellulaire à congeler, d'un liquide hydrophobe constituant une barrière transitoire entre le filtre et la suspension cellulaire. Lors de la décongélation, il est éliminé lors d'application d'une force d'entraînement, qui lui fait traverser le filtre.
