Fig. 2From: GMP-production of purified human B lymphocytes for the adoptive transfer in patients after allogeneic hematopoietic stem cell transplantationImmunophenotype of individual fractions from the two-step separation protocol. Density plots of combined stainings with CD45 PerCP, CD20-FITC and CD3-APC antibodies. 1 leukapheresis before thrombowash; 2 after thrombowash; 3 after binding of CD3 beads; 4 target fraction after CD3 depletion; 5 non-target fraction after CD3 depletion; 6 after binding of CD19 beads; 7 target fraction after CD19 enrichment; 8 non-target fraction after CD19 enrichment. Flow cytometry density plots of one representative separation performed under GMP conditions are shownBack to article page
