Microscopic measurements of IGROV1 : U937 cell interactions

Treatment	Untreated U937 % E : T contact (mean ± SD)	IL-4-treated U937 % E : T contact (mean ± SD)	IL-4-treated U937 % IGROV1 phagocytosis (mean ± SD)	FcεRI-transfected U937 % E : T contact (mean ± SD)
MOv18 IgE	24.6 ± 14.2	51.4 ± 17.7	43.5 ± 17.0	24.2 ± 9.6
NIP IgE	10.0 ± 7.5*	13.9 ± 12.7***	10.6 ± 8.4***	7.2 ± 7.2***
MOv18 IgE + IDEC-152 Fab	21.3 ± 16.3n/s	26.1 ± 12.8**	8.0 ± 5.4***	26.5 ± 11.4n/s
MOv18 IgE + sFceRIa	11.9 ± 8.9*	15.7 ± 16.5**	7.5 ± 6.8***	12.1 ± 8.6*

Data were collected by counting effector : target cell contact or target cell phagocytosis per microscopic field and percent values were calculated. Mean values were calculated from ten microscopic fields for each sample condition and are shown ± SD. Student’s t-test was used to generate significance of values compared to samples given MOv18 IgE
