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.

摘要:A method is provided for the synthesis of a mesoporous lithium transition metal compound, the method comprising the steps of (i) reacting a lithium salt with one or more transition metal salts in the presence of a surfactant, the surfactant being present in an amount sufficient to form a liquid crystal phase in the reaction mixture (ii) heating the reaction mixture so as to form a sol-gel and (iii) removing the surfactant to leave a mesoporous product. The mesoporous product can be an oxide, a phosphate, a borate or a silicate and optionally, an additional phosphate, borate or silicate reagent can be added at step (i). The reaction mixture can comprise an optional chelating agent and preferably, the reaction conditions at steps (i) and (ii) are controlled so as to prevent destabilization of the liquid crystal phase. The invention is particularly suitable for producing mesoporous lithium cobalt oxide and lithium iron phosphate. The method can be used to synthesize mesoporous lithium cobalt oxide having a specific surface area in excess of 10 m 2 /g, preferably 15 m 2 /g or more.

摘要:The present invention relates to cationic and polycationic compositions and methods for enhancing synthesis of nucleic acid molecules. In a preferred aspect, the invention relates to inhibition or control of nucleic acid synthesis, sequencing or amplification. Specifically, the present invention discloses cationic and polycationic molecules, compounds, and compositions having affinity for double-stranded and/or single-stranded nucleic acid molecules and/or single-stranded/double-stranded nucleic acid complexes (e.g., primer/template complexes, double-stranded templates, single-stranded templates or single-stranded primers) for use in such enhanced synthesis. The cationic and polycationic molecules, compounds, and compositions of the invention are capable of inhibiting nonspecific nucleic acid synthesis at ambient temperature. Thus, in a preferred aspect, the invention relates to “hot startâ€? synthesis of nucleic acid molecules. Accordingly, the invention prevents non-specific nucleic acid synthesis at low temperatures, for example during reaction set up. The invention also relates to kits for synthesizing, amplifying, reverse transcribing or sequencing nucleic acid molecules comprising one or more of the cationic and polycationic molecules, compounds, and compositions of the invention. The invention also relates to compositions prepared for carrying out the methods of the invention and to compositions made after or during such methods. The invention also generally relates to compositions useful for inhibiting or preventing degradation of various nucleic acid molcules.
