  • Patent number: 9744217
    Abstract: The purpose of the present invention is to establish a novel therapy method for hyperbilirubinemia and therefore, to provide a bilirubin excretion enhancer. The present invention provides a bilirubin excretion enhancer comprising, as an active ingredient, a serum albumin domain II-like protein comprising a serum albumin subdomain IIA. In one embodiment, the serum albumin subdomain IIA has an amino acid sequence of SEQ ID NO: 1. in one embodiment, the serum albumin domain II-like protein is a serum albumin domain II. In one embodiment, the serum albumin domain II comprises the amino acid sequence of SEQ ID NO: 4.

  • Patent number: 7803759
    Abstract: A protein is efficiently nitrosylated with nitrogen monoxide by merely mixing S-nitrosoglutathione as a nitrogen monoxide donor with a protein solution containing a stabilizing agent comprising at least one compound or a combination of plural compounds selected from an N-acetylamino acid, a fatty acid, and a fatty acid salt. The method that enables efficient NO addition to a cysteine residue in un-nitrosylated protein without changing the structure of protein and hence provides NO to a living organism.
