Fig. 2. (A–E) Comparison of mean fluorescence intensity (MFI) of cell surface markers (CD235a, CD15, CD59, CD24, and FLAER) among fresh (a) and 4℃/room temperature (RT) stored whole blood (WB) specimens (b: ethylenediaminetetraacetic acid [EDTA] WB in 4℃; c: EDTA WB in RT; d: 10% PM70 WB in RT; e: Cyto-Chex WB in RT; f: TransFix WB in RT). In a box-and-whisker plot, the central box represents the values from the lower to upper quartile (25 to 75 percentile). The middle line represents the median. A line extends from the minimum to the maximum value.
