摘要:Compositions, methods and kits for in vitro systems for synthesis of biomolecules such as polypeptides, are provided herein. Cell extracts that provide enhanced yields of soluble proteins using in vitro protein synthesis methods are provided. The invention also includes methods for producing high yields of proteins by the addition of a feeding solution that includes amino acids and an energy source to an ongoing in vitro synthesis system. The invention also includes methods of using a high-yield in vitro synthesis system to produce large quantities of proteins with incorporated labeled amino acids for analysis by methods such as by NMR. The invention further includes vectors for enhanced production of proteins from nucleic acid templates using in vitro synthesis systems.
