Protein Extinction Coefficient Calculator vs Beer-Lambert Law Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Protein Extinction Coefficient Calculator
Estimates a protein's molar extinction coefficient at 280 nm from its tryptophan, tyrosine, and cysteine residue counts. Used to calculate protein concentration from UV absorbance measurements.
- Answers
- Extinction Coefficient (M⁻¹cm⁻¹)
- Inputs
- Tryptophan Count, Tyrosine Count, Cysteine Count
Beer-Lambert Law Calculator
Find the concentration of a solution from its absorbance, molar extinction coefficient, and path length using Beer-Lambert law, with optional temperature correction. Widely used in spectrophotometry and analytical chemistry labs.
- Answers
- Concentration (M)
- Inputs
- Absorbance, Molar Extinction Coefficient, Path Length, Temperature, Solvent
