F4-150

Concentration of IVIGs: 25 mg/mL.

F4-151

Expressed as percentage of granulocytes that had ingested FITC-labeled E coli, with indication of the standard deviation. IVIG preparations were mixed with an equal volume of fresh plasma, added to unfractionated blood cells and FITC-labeled E coli and incubated for 10 minutes at 37°C. Phagocytosis activity of granulocytes was analyzed by FACS.
