Figure 3.
Effects of FMLP and RBC supernatants on the intracellular calcium levels in human neutrophils. Neutrophils (2.5 × 106) were loaded with Fura-2 AM, and fluorescence changes (ΔF) were monitored before and after exposure to RBC supernatant (1:1 × 105, vol/vol dilution) or FMLP (10 nM). Downward arrow indicates the stimulus addition. Results represent 1 of 3 experiments that yielded similar results.
