Cell type and antibody	Opsonin
	HoloBPI	Serum	None
Neutrophils	100.0	63.4	1.6
+MY4	105.6	88.1	3.5
+αCR3	100.7	21.7	2.1
Monocytes	16.4	65.6	0.0
+MY4	28.0	69.9	0.7
+αCR3	28.0	35.0	1.0

Bacterial uptake is expressed as a percentage of uptake by PMN of BPI-treated bacteria (=100%). The data shown represent the mean of two experiments.
