Results from DHR FACS oxidase analysis of 17-day cultures of differentiating CD34⁺ cells. Analyses were performed as in Fig 4. The bars represent the percent of cells in the region defined by mature high-oxidase positive granulocytes (those to the right of the line set in Fig 4). Bar A is the average of analysis of seven normals. Bars B through F represent the average value of four experiments for each bar seen. Bar B is sham treated patient cells, bars C through F are patient cells transduced with MFGS-p67^phox derived from clones 2, 5, 20, 37, respectively. Error bars represent standard error of the mean.
