Abstract
The changes in cytosolic Ca concentration in rat basophilic leukemia cells (RBL-2H3) were determined using a fluorescent Ca probe, fura-2, after aggregation of IgE receptors. By means of a superfusion system, both histamine secretion and changes in cytosolic Ca concentration were determined simultaneously. In addition, the microscopic observation revealed the oscillatory Ca signal after stimulation with an antigen.
摘要
在IgE受体聚集后，使用荧光钙探针fura-2测定大鼠嗜碱性白血病细胞（RBL-2H3）胞质钙浓度的变化。通过灌流系统，同时测定组胺分泌和胞质钙浓度的变化。此外，显微镜观察显示用抗原刺激后出现振荡性钙信号。
