Biological Activity for FURA-2AM

FURA-2AM is a fluorescent ratiometric Ca²⁺ indicator (K_d 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.
