20080206811 | Process For Producing Polypeptide - A process for producing a target protein at low temperature, comprising inducing expression of not only a vector having introduced therein a gene coding for the target protein but also a vector having a chaperone gene introduced therein. | 08-28-2008 |
20090047705 | MICROORGANISM-DERIVED PSYCHROPHILIC ENDONUCLEASE - A polypeptide having an endonuclease activity derived from a psychrophilic microorganism | 02-19-2009 |
20090098610 | Polypeptides having dna polymerase activity - A polypeptide having a high fidelity DNA polymerase activity and thus being useful as a genetic engineering reagent; a gene encoding this polypeptide; a method of producing the polypeptide; and a method of amplifying a nucleic acid by using the polypeptide. | 04-16-2009 |
20110097722 | Cold Shock Protein Compositions and Methods and Kits for the Use Thereof - The present invention provides cold shock protein-containing compositions for improved DNA synthesis reactions with improved reactivity, methods for synthesizing DNA using such compositions, kits for use in such methods, and DNA compositions yielded by such methods. The present invention further provides cold shock protein-containing compositions for the identification of endoribonuclease cleavage sites, methods for identifying endoribonuclease cleavage sites using such compositions, and kits for use in such methods. | 04-28-2011 |
20110151467 | COMPOSITION FOR DETECTION OF RNA - A composition for use in amplifying cDNA synthesized by a reverse transcription reaction and detecting RNA that serves as a template of the reverse transcription reaction, the composition containing a thermostable DNA polymerase, a thermostable ribonuclease H, and an intercalating dye. Since the composition of the present invention can suppress the influences to the nucleic acid amplification reaction by RNA that serves as a template for cDNA synthesis, the composition is useful in the detection of RNA, and more useful in quantification of RNA having a desired sequence by real-time RT-PCR. | 06-23-2011 |
20110278229 | Centrifugation Method - A centrifugation method for separating a high specific gravity substance and a low specific gravity substance from a mixture thereof, which prevents the contamination of the high specific gravity substance in collecting the low specific gravity substance after a separation operation, is provided. The centrifugation method includes centrifuging a mixture comprising a high specific gravity substance, a low specific gravity substance, and at least one of a thermoreversible gel and a dissolved gelling agent capable of forming a thermoreversible gel, in which the thermoreversible gel or the dissolved gelling agent forms a gel layer which separates the low specific gravity substance and the high specific gravity substance. The centrifugation is preferably carried out at a temperature equal to or lower than the gelation temperature of the gelling agent. | 11-17-2011 |
20120021420 | Synthetic siRNA Detection Method - A method for accurately and easily detecting a synthetic siRNA, for example, a siRNA in which the 3′ end is DNA, and a kit used for the method are provided. The present invention relates to a method for detecting a siRNA in which the 3′ end is DNA, comprising: (a) adding polydeoxyadenosine to the 3′ DNA end of at least one strand of the siRNA to be detected to produce a polydeoxyadenosine-added RNA; (b) annealing a polydeoxythymidine primer having a tag sequence at its 5′ side to the polydeoxyadenosine-added RNA and synthesizing DNA from the primer by a reverse transcription; and (c) detecting the DNA synthesized in (b). | 01-26-2012 |
20130295576 | METHOD FOR MODIFYING NUCLEIC ACIDS - The present invention pertains to: a method for modifying a nucleic acid contained in a sample, said method including a step for bringing the sample into contact with a nucleic acid-modifying agent in the presence of an acidic polysaccharide and/or a nucleotide; and a method for selectively detecting a nucleic acid derived from living cells contained in the sample, said method including the following steps: (a) a step for modifying a nucleic acid contained in a sample according to the method for modifying a nucleic acid contained in a sample, which includes a step for bringing the sample into contact with a nucleic acid-modifying agent in the presence of an acidic polysaccharide and/or a nucleotide; and (b) a step for selectively detecting an unmodified nucleic acid from the sample after step (a). The present invention further pertains to a kit and composition for use in these methods. | 11-07-2013 |
20140363849 | METHOD FOR IMPROVING NUCLEIC ACID SYNTHESIS REACTION - Provided are the following: a method, for improving reactivity of a nucleic acid synthesis reaction, comprising a step for adding an ω-amino acid to a reaction solution; a composition, for a nucleic acid synthesis reaction, comprising DNA polymerase, reaction buffer, at least one primer, at least one deoxyribonucleotide triphosphate, and an ω-amino acid; and a reaction buffer, for a nucleic acid synthesis reaction, comprising an ω-amino acid. | 12-11-2014 |
