生物活性 for FURA-2AM
FURA-2AM is a fluorescent ratiometric Ca2+ indicator (Kd Ca2+ = 145 nM). FURA-2AM is selective for Ca2+ over other divalent cations Mg2+, Zn2+, Fe2+ and Mn2+. FURA-2AM binds to free intracellular calcium and is used to determine [Ca2+]i concentration.
This product is typically prepared in DMSO. F 127 (Cat. No. 6253) for the solubilization of FURA-2AM is also available.

Detects store-operated Ca2+ entry after ER store depletion in RBL-2H3 cells..
By
Niroj Shrestha on 11/02/2018
分析类型： In Vitro
种属： Rat
细胞系/组织： RBL-2H3
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+.

细胞系/组织： primary ventricular cardiomyocytes
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.
