RBL-2H3 cells at a confluency of 50–60% were cultured on glass coverslip and loaded with 2 μM Fura-2AM in normal tyrode solution (NT) for 40 min at room temperature in the dark. Then, the cells were washed twice and left to equilibrate for at least 20 min in NT. The Fura-2 loaded cells were excited alternately at 340 and 380 nm and fluorescence was captured at 510 nm every 1.2 s. ER Ca2+ store was depleted with 500 nM thapsigargin which promotes store-operated Ca2+ entry into the cells upon addition of 2 mM extracellular Ca2+.
Primary guinea pig ventricular cardiomyocytes were loaded with FURA-2AM (1 μM) and Pluronic F 127 (1%) for 30 min followed by washing with normal-Tyrode solution. Cells were stimulated at 1 Hz frequency and fluorescence intensities were measured.
Used in live cell calcium imaging assay to study glutamate receptor signaling in neurons. Used at a concentration of 5 micromolar (along with pluronic). Images shows changes in fura-2 fluorescence pre (left) and post(right) glutamate stimulation.
