Purity assessment of CD34+ cell fraction after one or two column separations. A) The CD34+ cell fraction was 78% pure after the first column separation. B) A 92% pure CD34+ cell faction was obtained by an additional labeling step in connection with a second column separation. CD34+ cell populations were defined by first gating on forward and side scatter properties excluding platelets and debris. Subsequent gates were set to exclude >99% of control cells labeled with isotype-specific antibody. Percentages indicating the purity of isolated cell fractions are shown for both plots. Abbreviations: SSC, side scatter; PE, phycoerythrin.
