Webb15 jan. 2024 · In this equation KD is the dissociation constant for Ca 2+ -FURA-2 and was set to 224 n m (Westerblad & Allen, 1991 ). β is the fluorescence ratio between high and no [Ca 2+] c at 380 nm. Rmin and Rmax are the fluorescence ratios when Ca 2+ -FURA-2 binding is absent and saturated, respectively.
