We have devised a method for the purification of human basophils from umbilical cord blood by FCM. Umbilical cord blood was collected from six healthy, full-term deliveries. After separation of red blood cells, mononuclear cells were isolated by Ficoll-Hypaque. Six samples followed by positive selection using flowcytometry (FCM) for CD203c(+)CD45(int+) cells. Purity and recovery of cells were measured. Purity and recovery of basophils by FCM with CD203c(+)CD45(int+) markers were 95.02 +/- 2.94% and 61.42 +/- 5.95%. Cell sorting for CD203c(+)CD45(int+) cells by FCM is an improved method for obtaining pure umbilical cord blood-derived basophils. We established cord blood-derived basophil purification technique as a source from which active basophils can be isolated for immunochemical characterization.
