  • Patent number: 9442324
    Abstract: A source line is provided on a layer above a substrate, and as a whole, extends in a first direction while meandering along the main surface of the substrate. An alignment film is provided on a layer above the source line, and specifies the alignment direction of a liquid crystal. A first protruding section along the source line is formed on the surface of the alignment film. In a cross-section that is parallel to the first direction and perpendicular to the substrate, and that passes through the source line, the inclination of an inclined end face on one side of the first protruding section in the first direction is steeper than the inclination of each inclined end face on the other side of the protruding section.

  • Patent number: 5986062
    Abstract: Human serum albumin obtained by gene manipulation techniques can be purified by a combination of specified steps in which a culture supernatant obtained from a human serum albumin-producing host is subjected to ultrafiltration, heat treatment, acid treatment and another ultrafiltration, followed by subsequent treatments with a cation exchanger, a hydrophobic chromatography carrier and an anion exchanger, and by salting-out to thereby obtain a pure form of human serum albumin which contains substantially no proteinous and polysaccharide contaminants, which is formulated into a pharmaceutical preparation. The thus obtained human serum albumin can further be purified by treating recombinant human serum albumin with a hydrophobic chromatography carrier at pH of 2 to 5 and a salt concentration of 0.4 to 1 and exposing the carrier to a pH of 6 to 8 and a salt concentration of 0.01 to 0.

  • Patent number: 5710253
    Abstract: A method for decoloring a recombinant human serum albumin by treating the albumin with a reducing agent is disclosed. Also, a method for decoloring a recombinant human serum albumin by treating the albumin with a method removing free polysaccharides with a cation exchanger followed by heat treatment is disclosed. The present invention provides a recombinant human serum albumin, coloring of which is fully suppressed by preventing binding of certain coloring components, which are contained in the raw materials or contaminants secreted by a microorganism, to human serum albumin so as not to cause coloring of the human serum albumin.
