We have established a molecular diagnosis system for quantifying proteomic alterations of cancer drug resistance using wheat germ cell-free protein synthesis system and quantitative mass spectrometry. Stable isotope (SI) labeled recombinant proteins as an internal standard for protein quantification were in vitro synthesized using wheat cell-free synthesis system. We selected a set of digested peptides for each protein based on their ionization efficiency and established multiple reaction monitoring (MRM) assay using triple quadrupole mass spectrometer. We are currently constructing an absolute quantitative platform of human biopsy samples by combining MRM assay and synthesized SI-labeled protein library, which allows an accurate measurement of the absolute amount of targeted proteins from a limited amount of tissue samples.
