Data are reported as means plus or minus one standard deviation (SD). Unit A is the galactosylated unit from a donor, and unit B is the control unit from the same donor. Platelet recoveries and survivals are reported as uncorrected (uncorr) or corrected (corr) for elution of the radiolabel during storage and for residual radioactivity bound to red cells (see Methods section on evaluating platelet radiolabeling results).

— indicates not applicable; and SD, standard deviation.

Storage temperature was 4°C.

†

Storage temperature was 22°C.
