Table 1.

Immunostaining results of surfaces immobilized with E-selectin, anti-EpCAM, and mixtures of the two proteins.

	Anti-EpCAM (1.5 μg)	E-selectin (1.5 μg)	Anti-EpCAM (1.5 μg):E-selectin (0.3 μg)	Anti-EpCAM (1.5 μg):E- selectin (1.5 μg)	Anti-EpCAM (1.5 μg):E- selectin (7.5 μg)
FITC-anti-E- selectin (for E-selectin detection)	-	1	0.04 ± 0.01	0.66 ± 0.06	1.31 ± 0.02
APC-anti- EpCAM (for anti-EpCAM detection)	1	-	0.88 ± 0.31	0.96 ± 0.70	0.61 ± 0.31

Note that all the fluorescence intensities were normalized based on the intensities measured on the surfaces with individual proteins.
