Histograms of the number of detections. (A) For each timed granulocyte DNA sample analyzed by LAM-PCR and Gene Scan from animal 95E003, a histogram is depicted showing the number of detections (of a maximum of 18 possible) on the x-axis and the number of clones with that frequency of detection on the y-axis, including all clones detected (n = 90) at any time during the pretreatment baseline samples (histograms i-viii), during G-CSF (histograms ix and x), following G-CSF (histograms xi-xiv), during G-CSF plus SCF (histograms xv and xvi), and following G-CSF plus SCF (histograms xvii and xviii). The mean number of detections per clone is shown as the solid dot. After 2 months of G-CSF, for instance, histogram x shows that 33 clones were detected zero times, 21 clones were detected 1 time, 15 clones were detected 2 times, 6 clones were detected 3 times, and so forth. (B) The same analysis for animal RQ2265, with histograms ix and x obtained on G-CSF and SCF.
