Granulocytes storage temp
WebGranulocyte product collected by centrifugation leukapheresis from G-CSF-stimulated donors can be effectively stored at subphysiologic temperature for 24 hours with preservation of functional activity. Storage at 10 degrees C appears to be slightly superior to storage at 22 degrees C. WebNov 16, 2015 · According to current standards, granulocyte storage should be limited to 24 h. After 2 days of storage in RPMI-1640 medium at 4 °C, only 2–7 % of the granulocytes remain viable . Infusible solutions to be used in place of autologous plasma have been designed and tested with the aim of improving granulocyte storage.
