High-throughput synthesis of stable isotope-labeled transmembrane proteins for targeted transmembrane proteomics using a wheat germ cell-free protein synthesis system.

Using a wheat germ cell-free protein synthesis system, we developed a high-throughput method for the synthesis of stable isotope-labeled full-length transmembrane proteins as proteoliposomes to mimic the in vivo environment, and we successfully constructed an internal standard library for targeted transmembrane proteomics by using mass spectrometry.
