| In Vitro | Mag-Indo-1 tetrapotassium salt can be used to determine the free Mg2+ concentration in the cytoplasmic solutions[1]. Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs)[1]. 1. Calibrating solutions containing various concentrations of Mg2+ are prepared by mixing different ratios of the two stock solutions: one contains (mM) 150 KCl, 0.1 EGTA and 5 Hepes (pH 7.2 with KOH), and the other contains 100 MgCl2, 0.1 EGTA and 5 Hepes (pH 7.2 with KOH). 2. The calibration curve is constructed using calibrating solutions containing 1 μM Mag-Indo-1 tetrapotassium salt. 3. The ‘Mg2+’ calibrating solution contained (mM): 130 KCl, 4 EDTA and 5 Hepes (pH 7.2 with KOH). 4. The relationship between the background-corrected value of the fluorescence ratio (R) and the Mg2+ concentration is fitted with the following theoretical equation. [Mg]=K (R-Rmin)/(Rmax-R), where [Mg] is the concentration of free Mg2+ ion, Rmin is the R value at 0 [Mg2+], and Rmax is the R value at saturating Mg2+. The curve fitting gave Rmin= 0.053, Rmax= 1.57, and K= 5.1 mM. Note: the specific curve can refer to the reference. |
