  • Publication number: 20060292667
    Abstract: Disclosed is a method for improving folding efficiency and solubility of a target protein linked to a RNA-binding protein by using RNA molecule as a molecular chaperone, wherein the RNA molecule interacts with the RNA-binding protein. More particularly, the present invention discloses method for improving folding efficiency and solubility of a target protein by transformation of a host cell with a expression vector comprising a polynucleotide encoding the target protein linked to an RNA-binding protein; culturing the transformed host cell in an appropriate culture medium under the condition that an RNA molecule either resident inside the host cell or provided by cotransformation of the host cell with polynucleotide encoding the RNA molecule interacts with the RNA-binding protein; and purifying the soluble protein from host cell lysate. The method of the present invention is very useful for production of soluble proteins for therapeutic, prophylactic and diagnostic applications.

  • Publication number: 20060252204
    Abstract: A method of manufacturing a flash memory device wherein a stacked structure of an oxide and nitride or the reverse is applied to insulation spacers provided on sidewalls of gates for forming source/drain regions. After completing the source/drain regions, spacers are formed on sidewalls of the gates by using an oxide film as a contacting buffer, thus minimizing the interference between gates and reducing the stress to cells, overcoming the disturbance of threshold voltage.

  • Publication number: 20050204433
    Abstract: The objective of this invention is to enhance the efficiency of plastid transformation using nuclear transformed plants in which the microbial recombinase A(recA) is to target to (or expressed in) the plastid. This invention will be better explained by the following detailed descriptions. A plant is transformed with a nuclear transformation vector containing the microbial recA gene added with a plastid targeting sequence. In this nuclear transformed plant, the frequency of plastid transformation is enhanced greater than two-folds due to increased homologous recombination between the plastid transformation vector carrying genes of interest (or target genes) and the plastid genome. In addition, because plastid transformation is accomplished through a gradual process, adventitious shoots selected after being subjected to plastid transformation should be cut into explants, and then shoots regenerated from the explants are to be reselected until all of the plastids in the shoots are uniformly transformed.
