Figure 4.

Storage in additive solution or treatment with Irradiation, mirasol, or intercept does not induce formation of cross-linked adducts of endogenous platelet RNAs. The figure shows the lack of cross-linked adducts of endogenous platelet RNAs that can be attributed to treatment with additive solution, Irradiation, mirasol or intercept, as compared with no treatment (control), at any time point (day 1, 4, or 7 of storage) by total RNA extraction, dephosphorylation, ³²P labeling, and analysis by denaturing PAGE. Compare with Supplementary Figure S4, which shows the results without dephosphorylation.
