[Exclusion chromatography for the separation of cryoprotective agents from freeze-preserved blood cells].

Abstract

A method for separating low molecular cryoprotectiva from freeze-conserved erythrocyte- and thrombocyte-concentrates by exclusion chromatography has been described. A new vesicular packing material has been used. Only 25 to 30 minutes are necessary in order to separate glycerol respectively dimethylsulphoxide (DMSO) completely from the cells. 86.5% of the erythrocytes and 75.4% of the thrombocytes were recovered after the separation process.
