An efficient granulocytes preservation would allow an easier study of their structure and functions, of granulocytes functional diseases (e.g. chronic granulomatous disease) and an easier use of granulocytes as a clinical tool (e.g. for localizing infections or for transfusions). Unfortunately, granulocytes are nearly impossible to preserve, even in a short-term storage (less than 24 hours). This study proposes an experimental model which could improve in vitro granulocyte functions maintenance. Bicarbonate buffer, glucose, adenosine triphosphate, vitamins C and E, nicotinamide adenine dinucleotide, nicotinamide adenine dinucleotide phosphate, amikacin, and ampicillin supplementation significantly (p 0.05) improve maintenance of one or several granulocyte functions during storage.
