[ Product Description ]
Magnesium is one of the most abundant minerals in the living cells, and plays important roles in many metabolic reactions
such as polyphosphoric acid formation and photosynthesis in the chlorophyll.
[ Assay principle ]
Under alkaline condition, Xyridyl Blue-I(XB-I) - magnesium complex shows absorbance at 520 nm, and on the other hand,
the absorbance by free XB-I at 600-680nm decreases.
[ Performance ]
1. Sensitivity:
2. Accuracy:
3. Intra assay variation:
4. Assay range: |
O.D. at 2 mg/dL standard will be 0.05 - 0.1(660nm vs 700nm)
±15% of known concentration
C.V. is less than 5%
0.05 - 3.5 mg/dL |

| [ Specifications ] |
| Principle: |
XB-I method (Colorimetric assay at 520-660 vs 700 nm)
Measuring wavelength: 660nm (reference 700 nm) is recommended.
Measuring at 520 nm vs 700 nm shows higher sensitivity but may be susceptible to various factors. |
| Specifity: |
Magnesium (Mg) |
| Assay range: |
0.05 - 3.5 mg/dL |
| Assay condition: |
5 minutes at room temperature (25 - 37 °C) |
| Applications: |
Serum, urine, saliva, cell lysate, tissue extract, plant extract,
hair extract, food extract and water.
This assay will be interfered by EDTA, hemoglobin, anticoagulants and high concentration of potassium. |
