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:An object of the present invention is to provide a method of treatment and a method of storage that are useful in conducting a nucleic acid synthesis procedure capable of directly amplifying an intended nucleic acid in a living body-derived sample without purification steps.The present invention provides a method for synthesis of nucleic acids in which a living body-derived sample itself is mixed with a reaction solution for gene amplification and allowed to react, which method comprises treating the sample with a surfactant before the reaction to destruct solid components such as cells or bacterial bodies containing nucleic acids and uniformly disperse them in the sample liquid.

标 题 :Synthesis of pharmaceutical compositions with lactams and β-lactams/oxo thia azabicyclo compounds
发明人：THIRUMALACHAR MANDAYAM JEERSAN; NARASIMHAN JR MANDAYAM JEERSAN
摘要:Pharmaceutical compositions with heretofore unknown and enhanced physical, chemical, and biological properties are prepared by combining known biologically active parent compounds with oxo thia azabicyclo compounds, such as lactam and beta -lactam compounds, capable of rapidly transporting the parent compounds in undegraded form to their target sites of action. A process for combining the parent compound with beta -lactam compounds consists of dissolving the parent compound in a polar solvent, adding a beta -lactam compound, incubating the resulting mixture, followed by drying, and subjecting the remaining solid material to solvent washing or extraction to further purify the new pharmaceutical composition. The new pharmaceutical composition possesses the biological and therapeutic activity of the parent compound and the barrier penetrating characteristics of the beta -lactam compound, which results in improved pharmacodynamics, including bioavailability, and an improved chemotherapeutic index, such that lower amounts of the parent may be used to avoid the toxic effects of the parent compound. Some of the new pharmaceutical compounds provide for the first time parent compounds in an orally administerable form.

标题 :Method of producing milk factor
发明人：MANN GEORGE V
权利人:UNIV VANDERBILT
摘要:The substance naturally present in milk (referred to as Milk Factor or MF) which is capable of inhibiting mammalian synthesis of cholesterol is produced by a fermentation process using a culture of Pseudomonas fluorescens loitokitok or other Milk Factor-producing strain of P. fluorescens in a culture medium containing glutaconic acid. The process may be used to increase the Milk Factor content of milk, yogurt, or similar dairy product, or the Milk Factor may be recovered from a culture medium and concentrated, crystallized and used as a food additive.
