摘要:Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated carrier proteins. The glycosylated carrier proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated carrier proteins may include a bacterial polysaccharide conjugated to a carrier, which may be utilized to generate an immune response in an immunized host against the polysaccharide conjugated to the carrier. The glycosylated carrier proteins may be synthesized in cell-free glycoprotein synthesis (CFGpS) systems using prokaryote cell lysates that are enriched in components for glycoprotein synthesis such as oligosaccharyltransferases (OSTs) and lipid-linked oligosaccharides (LLOs) including OSTs and LLOs associated with synthesis of bacterial O antigens.

摘要:Compositions and methods are provided for the cell-free synthesis of active reprogramming factor polypeptides. The reprogramming factors may be synthesized as fusion proteins comprising a permeant domain, such as polyarginme. The cell free-synthesis may be conducted at about 25 C in a bacterial cell extract from genetically alterd cells having decreased endogenous protease activity Further, the proteins may comprise a fusion partner which enhances solubility and may be refolded on a column.

摘要:Compositions and methods are provided for the in vitro synthesis of biological molecules in reaction mixtures comprising anti-foam agents. The reaction mix comprising antifoam agent may be a scaled up reaction, e.g. in reaction volume greater than at least about 15 μl. Reactions may be performed in various reactors, as known in the art, which include stirred reactors, bubble-column reactors; and the like.

标 题 :Synthesis of linear and branched polymers of polypeptides through direct conjugation
发明人：ALBAYRAK CEM; SWARTZ JAMES R; LU YUAN
权利人:UNIV LELAND STANFORD JUNIOR
摘要:Methods are provided for a one step synthesis of polypeptide polymers or co-polymers. The polymers or co-polymers can be linear or branched. In the methods of the invention, the coding sequence for the polypeptide(s) to be polymerized is altered by introducing one or more codons for an nonnatural amino acid, which coding sequence is then utilized to produce the cognate polypeptide. The nonnatural amino acids are selected to be reactive with each other in a bioorthogonal reaction, and are combined in a conjugation reaction with the desired components of the polymer.
