  • Publication number: 20240105899
    Abstract: A method of manufacturing a display device includes aligning light emitting elements in an emission area on a substrate, depositing an indium-tin alloy on an entire surface of the substrate at room temperature, heat-treating the indium-tin alloy to reflow along side surfaces of each of the light emitting elements, heat-treating the indium-tin alloy in an oxygen atmosphere to form indium tin oxide, and etching the indium tin oxide to form a first pixel electrode contacting first ends of at least a portion of the light emitting elements.

  • Patent number: 8569016
    Abstract: The present invention aims to express influenza virus RNA polymerase on a large scale, to crystallize the influenza virus RNA polymerase, and to provide a method for screening a substance capable of serving as an active ingredient in anti-influenza drugs. The present invention provides a complex comprising a polypeptide consisting of an amino acid sequence at positions 678-757 of the RNA polymerase PB1 subunit in influenza A/Puerto Rico/8/34 H1N1 (SEQ ID NO: 2) and a polypeptide consisting of an amino acid sequence at positions 1-37 of RNA polymerase PB2 subunit in influenza A/Puerto Rico/8/34 H1N1 (SEQ ID NO: 4). This complex can be crystallized in the presence of a precipitant such as potassium phosphate and PEG4000. Moreover, with the use of information on the crystal structure of this complex, it is possible to provide a method for screening a substance capable of serving as an active ingredient in anti-influenza drugs.

  • Patent number: 8455229
    Abstract: The present invention aims to express influenza virus RNA polymerase on a large scale, to crystallize the influenza virus RNA polymerase, and to provide a method for screening a substance capable of serving as an active ingredient in anti-influenza drugs which target a protein highly conserved among influenza virus species. The present invention provides a complex comprising a polypeptide consisting of an amino acid sequence at positions 239-716 of the RNA polymerase PA subunit in influenza A/Puerto Rico/8/1934 H1N1 and a polypeptide consisting of an amino acid sequence at positions 1-81 of the RNA polymerase PB1 subunit in influenza A/Puerto Rico/8/1934 H1N1, as well as a method for screening a substance capable of serving as an active ingredient in anti-influenza drugs, which comprises the step of selecting a substance which inhibits the interaction between ?-subunit and ?-subunit 1, each constituting influenza virus RNA polymerase, in the presence of a candidate substance.
