Inorganic phosphorus primarily refers to inorganic phosphate ions, which participate in various metabolic processes within organisms, including energy metabolism, nucleic acid metabolism, and protein phosphorylation/dephosphorylation. Furthermore, it promotes the synthesis, transformation, and transport of carbohydrates.
Assay Principle:Ammonium molybdate reacts with inorganic phosphate ions to form a complex with a characteristic absorption peak at 660 nm. The inorganic phosphorus content is calculated by measuring the absorbance at 660 nm.
Applicable Samples: Animal and plant tissues

Add 1 mL of Reagent I (using a ratio of tissue mass (g) : Reagent I volume (mL) = 1:10).
Homogenize in an ice bath.
Centrifuge at 10,000 g, 4°C for 10 minutes.
Collect the supernatant and keep on ice for assay.

3. Assay Procedure
3.1 Instrument Preparation
Preheat the microplate reader or visible spectrophotometer for 30 minutes. Set wavelength to 660 nm.
Zero the visible spectrophotometer with deionized water.
3.2 Assay Setup (Perform in 1.5 mL centrifuge tubes):
| Reagent (μL) | Blank Tube | Standard Tube | Test Tube |
| Sample Supernatant | 0 | 0 | 10 |
| Deionized Water | 100 | 90 | 90 |
| Standard | 0 | 10 | 0 |
| Phosphorus Assay Reagent | 100 | 100 | 100 |
3.3 Measurement
Mix well after addition.
Incubate in a 40°C water bath for 10 minutes.
Cool at room temperature for 10 minutes.
Transfer 200 μL of the supernatant to a micro glass cuvette or 96-well plate.
Measure the absorbance at 660 nm.
Record the values as ABlank, AStandard, and ATest. Calculate ΔAtest = ATest - ABlank and ΔAstandard = AStandard - ABlank.
Note: The Blank and Standard tubes need only be measured once.
A pilot experiment with 2-3 variable samples is recommended.
If ΔAtest is too small, consider increasing the sample amount.
If ΔAtest is greater than 1.0, dilute the sample further with Reagent I and multiply the result by the dilution factor, or reduce the sample amount used for extraction.
4. Calculation of Results
Note: We provide both the derived formula and the simplified formula for your convenience. They are mathematically equivalent. The bolded simplified formula is recommended for final calculations.
4.1 Based on Protein Content:
Derived Formula: Inorganic Phosphorus Content (μmol/mg prot) =(CStandard × ΔAtest ÷ ΔAstandard) × Vtotal ÷ Cpr
Simplified Formula: Inorganic Phosphorus Content (μmol/mg prot) = 1 × ΔAtest ÷ ΔAstandard ÷ Cpr
