Formula and methodology
Formula: Soluble concentration = soluble mass/volume; recovery = soluble mass/loaded mass × 100%; undissolved estimate = loaded mass − soluble mass.
This page reports the arithmetic behind a soluble-protein assay. It does not determine whether a protein is truly at equilibrium solubility, which depends on identity, pH, temperature, ionic strength, solvent, time, and the assay method.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Measured soluble protein — mg; minimum 0; maximum 1000000000
- Sample liquid volume — mL; minimum 1.0E-6; maximum 1000000000
- Protein loaded before separation — mg; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Measured soluble protein | 15 |
| Sample liquid volume | 10 |
| Protein loaded before separation | 20 |
Soluble concentration = 1.5 mg/mL, recovery = 75%, undissolved estimate = 5 mg.
Assumptions and limits
- The soluble mass and loaded mass use the same mass unit, and the sample volume represents the measured liquid fraction.
- The soluble measurement is not greater than the loaded protein mass in this recovery summary.
- Protein aggregation, degradation, assay bias, incomplete separation, and equilibrium behavior are not modeled.
