摘要:Testing the many hypotheses from genomics and systems biology experiments demands accurate and cost-effective gene and genome synthesis. Here we describe a microchip-based technology for multiplex gene synthesis. Pools of thousands of ‘construction’ oligonucleotides and tagged complementary ‘selection’ oligonucleotides are synthesized on photo-programmable microfluidic chips, released, amplified and selected by hybridization to reduce synthesis errors ninefold. A one-step polymerase assembly multiplexing reaction assembles these into multiple genes. This technology enabled us to synthesize all 21 genes that encode the proteins of the Escherichia coli 30S ribosomal subunit, and to optimize their translation efficiency in vitro through alteration of codon bias. This is a significant step towards the synthesis of ribosomes in vitro and should have utility for synthetic biology in general.

摘要:The present invention generally relates to the individual stereoisomers of the drug valnoctamide (a mixture of four stereoisomer kinds, VCD-valmethamide or 2-ethyl-3-methyl pentanamide) useful in treatment of neurological and psychotic disorders such as different kinds of epilepsy and affective disorders, and useful as tranquilizers and to treat pain, and to pharmaceutical compositions containing, as an active ingredient, these stereoisomers. The present invention further relates to a method for stereoselective separation and quantification of the four stereoisomers from a racemic mixture of VCD or plasma of patients treated with the racemic drug. The present invention further relates to a unique method for the synthesis of the individual stereoisomers.

标题:Synthesis of zeolites of small and uniform size having a high magnesium exchange capacity
发明人：KOSTINKO JOHN A
权利人:HUBER CORP J M
摘要:Zeolites of small and uniform size are formed having high magnesium exchange capacities. Zeolite A is disclosed having an average particle size less than 1.7 microns, a calcium carbonate exchange capacity of more than 230 mg calcium carbonate per gram zeolite and a magnesium exchange capacity of more than 140 mg magnesium carbonate per gram zeolite. This zeolite A is produced from a reaction mixture having a water to sodium oxide molar ratio of less than 35:1, and a sodium oxide to silica molar ratio of between 1:1 and 4:1, wherein the silica to alumina molar ratio is greater than 3:1 when the sodium oxide to silica molar ratio is less than 4:3 and the sodium oxide to alumina molar ratio is greater than 4:1 when the sodium oxide to silica molar ratio is greater than 4:3. Zeolite X is disclosed having an average particle size less than 2.2 microns, a calcium carbonate exchange capacity of more than 205 mg calcium carbonate per gram zeolite, and a magnesium exchange capacity of more than 130 mg magnesium carbonate per gram zeolite. This zeolite X is produced from a reaction mixture having a silicate alumina molar ratio greater than 5:1. A combination of zerolite A and zeolite X can be produced from the same reaction mixture.
