Absolute quantification of proteins: forget amino acid analysis and shift to the new gold standard

Absolute quantification of proteins (i.e. quantification without the need for a reference standard) is a key analysis for the qualification of reference standards or to determine the extinction coefficient of a protein. It is usually performed using amino acid analysis, but this techniqu
