Changes in the three blood forms nitrite levels over the duration of storage.

Figure 2. Time-dependent changes in nitrite concentration during storage. Blood components stored in the three forms noted were kept for 42 days at 4°C in either room air (2A) or an argon chamber (2B), to emulate aerobic and hypoxic conditions, respectively; number of donors, n=3 (A), n=3 (B). Supplemental Figure 2. Time-dependent room air and chamber changes in nitrite concentration for individual stored blood components; number of donors, n=3 (room air), n=3 (chamber).
