How To Calculate Protein Concentration From Absorbance 280, It can use extinction coefficients, sequence counts, dilution, path length, and correction readings. Basic Calculator Online Your trusted destination for free online calculator tools. . Mar 21, 2026 · How to use our Protein Concentration Calculator Choose "What do you know about your protein?" based on the number you already have: molar extinction coefficient, 1% absorptivity at 280 nm (E1%), or the quick estimate. If choosing protein extinction coefficient, UV absorbance at 280 nm by tryptophan and tyrosine residues is used for the calculation. The concentration of Protein in solution can be determined by substituting the molecular weight, extinction coefficient and λ max into a derived form of the Beer - Lambert Law. This website is designed to help you quickly and easily calculate percentages for a variety of purposes.
