Table 1. Characterization of contaminating leukocytes.

Samples, see Figure 2	A. Initial whole Blood Sample	B. CD4+ pluriSelect	C. CD8+ pluriSelect	F. CD4+ MACS	H. CD8+ MACS
Monocytes (CD14+ SSCmid) % of leukocytes	6.86 (5.93-8.22)	0.80 (0.50-2.00)	0.20 (0.16-0.29)	3.50* (2.30-4.10)	3.45* (2.45-4.90)
NK cells (CD16/56+ and CD16/56/8) % of lymphocytes	13.72 (10.26-17.16)	0.11 (0.05-0.19)	2.29 (1.01-5.73)	0.72* (0.59-1.35)	3.02 (1.45-3.98)
B lymphocytes (CD19+) % of lymphocytes	14.12 (9.73-16.22)	0.33 (0.14-0.52)	0.12 (0.08-0.18)	0.85* (0.55-1.13)	1.20* (1.02-1.90)

Table shows the summary for determination of contaminating leukocytes (n=11). Data show median and range in parenthesis. * shows significant differences between values obtained by MACS and pluriSelect (Sample F vs Sample B or Sample H vs. Sample C from Figure 2). It was regarded statistically significant if p<0.01 (Bonferroni corrected significance).
