WebThe extinction coefficient indicates how much light a protein absorbs at a certain wavelength. It is useful to have an estimation of this coefficient for following a protein … WebThe molar extinction coefficient of a pure protein at 280 nm (e 280) can be calculated from the number of tyrosine and tryptophan residues in the protein. The extinction coefficients at 280 nm for the individual amino acid side chains are 1200 M-1.cm-1 for tyrosine, and 5500 M-1.cm-1 for tryptophan. Phenylalanine does not absorb at 280 nm.
