Relative expression levels of selected miRNA during storage.

The miRNA in apheresis platelets are differentially expressed on days 1, 3 and 5 compared with on day 0, as determined by qRT-PCR. MiRNA whose expression changed at least 2-fold change are listed. Statistical analyses were performed using GraphPad prism 5 software. Results identified as significant were those that were more than 2-fold different between day 0 and day 5. The change for each miRNA represents the average found in five independent donors. Results are expressed as mean±standard deviation (SD) (*p<0.05 vs day 0).
