Calcium mobilization upon FcγR stimulation in BMMs from gene-targeted mice.
BMMs (5 × 105) from gene-targeted mice indicated were loaded with Indo-1 AM and stimulated with 40 μg/mL ΔIgG. The intracellular Ca++ was monitored by spectrofluorometry. The bar indicates intracellular Ca++ as a reference. The arrow indicates the time when ΔIgG was added.
