Abstract: In the method for introducing a noncanonical amino acid residue into a desired position in a protein, the structure of tRNA is so modified as to have improved affinity for aminoacyl-tRNA synthetase or improved specificity to aminoacyl-tRNA synthetase. An unnatural base is contained at any position in tRNA, whereby the efficiency of aminoacylation of the tRNA with a noncanonical amino acid can be improved.

Abstract: The invention provides a yeast strain and a method for making the same. The method has the step of replacing the regulation region upstream of the hsp104 gene in the genome of the yeast, so as to accelerate and prolong the expression span of hsp104 gene and enhance the capability of the yeast to ferment and produce ethanol in a high-temperature environment. The yeast is capable of fermenting glucose at a temperature higher than 42° C. to produce ethanol, or biomass ethanol, wherein the ethanol production ratio based on fermentation of glucose is higher than 97%. Being able to synchronize the degradation/hydrolysis stage and fermentation stage of biomass ethanol producing process, the yeast in accordance with the present invention is able to lower the production cost of biomass ethanol and further raise the productivity with its high ethanol production ratio.
Abstract: A method for preparing a sample by utilizing a shearing force in the presence of a size stabilizer to break apart the sample to obtain nucleic acid molecules in a usable size range. Once nucleic acid molecules are obtained, magnetic entanglement particles are used to concentrate and clean the nucleic acid molecules for further testing.

Abstract: The invention provides methods to detect molecular recognition events. The invention also provides methods to detect the presence of or identify a target species based on its interaction with one or more probe species. The methods of the invention are based on amplification of the signal due to each molecular recognition event. The amplification is achieved through photopolymerization, with the polymer formed being associated with the molecular recognition event. In one aspect, a fluorescent polymer, a magnetic polymer, a radioactive polymer or an electrically conducting polymer can form the basis of detection and amplification. In another aspect, a polymer gel swollen with a fluorescent solution, a magnetic solution, a radioactive solution or an electrically conducting solution can form the basis of detection and amplification. In another aspect, detectable particles can be included in the polymer formed. In another aspect, sufficient polymer forms to be detectable by visual inspection.
