Verfahren zur Stabilisierung und Langzeitkonservierung von roten Blutzellen

The invention relates to a process for the stabilization and long-term preservation or for the rejuvenation of erythrocytes, by which an erythrocyte concentrate is first recovered using known methods in themselves, whereby the erythrocyte concentrate is passed through at least one adsorber containing a cation modified polymer material and the erythrocytes leaving the adsorber are resuspended in a chloride-free additive solution.
