IVIG-derived F(ab’)2 fragments do not induce cell death of murine neutrophils. Flow cytometric analysis of cell death by annexin V-FITC/PI staining (a) or DNA fragmentation (b) of cells cultured in presence of 13.3 mg/ml F(ab’)2 or 110 ng/ml crosslinked Fas-L (positive control). Results of 15-hour cultures are shown. Data are representative of three independent experiments. Quantitative analysis is indicated as the percentage representative of each quadrant (a) or of gated subdiploid DNA (b)
