Duffy antigen changes on red blood cells stored at low temperature.
Red blood cells stored in saline solution for two weeks at 12 C lose some of their Fya, Fyb, and Fy3 antigenicity. At the same time substances with specific inhibitory activity against appropriate Duffy antibodies appear in the saline. Similar changes could not be recognized in time-expired commercial reagent red blood cell samples.
