Calculation Of Protein Extinction Coefficients From Amino Acid Sequence Data . 4 we calculate extinction coefficient for the protein in your buffer. For a given protein, the a 280 is proportional to its concentration of amino acids. Variations in Orf3a protein of SARSCoV2 alter its structure and from europepmc.org To determine the extinction/attenuation coefficient, you will need access to an amino acid analyzer and a spectrophotometer. First, hydrolyze the sample in hcl in triplicate and measure. Thus, a× (molecular weight of the protein)/ε molar =concentration in mg/ml.
