What is Quantitative Analysis of Tryptophan Analogue Incorporation in Recombinant Proteins about?
Three different methods to quantitate tryptophan (Trp) analogue incorporation into recombinant proteins are described: first, spectroscopic analysis based on a linear combination of the absorption spectra of the aromatic residues in the denatured Trp-containing or analogue-substituted protein; second, chromatographic separation of analoguesubstituted and Trp-containing proteins by HPLC; and third, mass spectrum analysis of the mixture of analogue-substituted and Trp-containing proteins. An accurate estimate of analogue incorporation in single-Trp proteins can be obtained directly by either analysis of the absorption spectrum or HPLC chromatography. While analysis of the absorption spectrum or HPLC chromatogram can provide an assessment of the average level of analogue incorporation for proteins that contain two or more Trp residues, mass spectroscopy analysis of peptides generated by protease digestion and separated by HPLC provides a general method for a complete quantitative description of the distribution of analogue incorporation. The more complex analysis by mass spectroscopy becomes important for multi-Trp proteins because the distribution of analogue versus Trp-containing po
