Preservation of neutrophils in CPD-adenine

Human neutrophils were stored in vitro in CPD or CPD-adenine plasma under conditions designed to simulate those of leukapheresis followed by short-term preservation. Viability, morphology by light microscopy, and phagocytic ability of cells stored in either anticoagulant were similar when studied sequentially during 72 hours of storage. Thus, CPD-adenine offered no advantage, under the conditions employed, over standard CPD without adenine.
