Murine BMMCs from female mice were loaded with Fluo 4 Ca2+ indicator and stimulated with indicated MC degranulation stimuli as described in the Material and Methods Section. Intracellular Ca2+ mobilization (presented as ∆F480/F540 or as representative traces) in response to indicated concentrations of IgE/DNP (A,E), A23187 (B,F) and c48/80 (C,G) and Carbachol (D,H). Data shown are the means ± SE and are representative of 3 independent experiments performed in triplicate. Data were analyzed using a 1-way ANOVA *P < 0.05, **P < 0.001, ***P < 0.0001.
