METHOD OF ISOTOPE LABELING AND DETERMINING PROTEIN SYNTHESIS, QUANTITATION AND PROTEIN EXPRESSION

A method including isotope labeling of a newly synthesized protein in a sufficient quantity such that a newly synthesized protein spectra and the pre-existing protein spectra are sufficiently separated. A further method including determining a ratio of a new and a pre-existing protein from mass spec...

Zusammenfassung:A method including isotope labeling of a newly synthesized protein in a sufficient quantity such that a newly synthesized protein spectra and the pre-existing protein spectra are sufficiently separated. A further method including determining a ratio of a new and a pre-existing protein from mass spectra obtained by using mass spectrometry. In this method a resultant spectrum may be presented as integrated peak heights for a corresponding mass to charge ratio in the "centroid" mode.
