[Comparison of erythrocyte concentrations of ATP, ADP, AMP and 2,3-BPG in storage of five different additive solutions and in serum].

In this study, we compared the ability of serum and of 5 additive solutions for the liquid storage of red blood cells to preserve the cellular contents of 2,3-BPG and the adenylate nucleotides ATP, ADP and AMP. As to the adenylates, PAGGS-M showed the best results. However, the difference to SAG-M was significant only after 7 weeks. On the other hand, serum appears to be the best medium for the conservation of 2,3-BPG. Between the 1st and 3rd week of storage, the decrease of 2,3-BPG was somewhat slower in PAGGS-M and SAG-M compared with the other 3 additive solutions.
