      Detection principle

      The magnesium in the serum reacts with the complexometric indicator (Calmagite) to form the Calmagite-Mg compound. The absorbance of this compound at 540 nm is proportional to the concentration of magnesium in the sample. The concentration of magnesium can be calculated by measuring the OD value at 540 nm.

      Dilution of sample

      It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.12-2.50 mmol/L).

      The recommended dilution factor for different samples is as follows (for reference only):

      Sample type

      Dilution factor

      Human serum


      Rat serum


      Mouse serum


      Porcine serum


      Chicken serum


      Dog serum


      Note: The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4).
