  • Publication number: 20090004725
    Abstract: The present invention intends to find out a gene participating in addition of mannose phosphate to a sugar chain of a glycoprotein originating in a yeast belonging to the genus Pichia and provide a means of controlling the same. The present invention also intends to provide a process for producing a protein with reduction of an acidic sugar chain by using the thus controlled yeast strain belonging to the genus Pichia. Namely, the present invention includes a protein participating in the addition of mannose phosphate to a sugar chain of a glycoprotein; a gene coding this protein; a mutant of this gene; a vector carrying the mutant gene; a yeast strain belonging to the genus Pichia having been transformed by this vector; a process for producing a protein with reduction of an acidic sugar chain by using the transformed yeast strain; and a glycoprotein thus produced.

  • Patent number: 7396915
    Abstract: A novel human monoclonal antibody specifically recognizing cancer cells such as non-small cell lung cancer, pancreatic cancer and gastric cancer cells is produced by hybridomas which are obtained by fusing lymphocytes derived from a cancer tissue of a cancer patient with mouse myeloma cells. An anti-cancer drug is obtained by using the antibody alone or anchoring the antibody on the surface of a liposome containing a toxin or an anti-cancer drug encapsulated therein. More specifically, an anti-cancer drug is obtained by using an antibody, in which variable region of its heavy chain comprises the amino acid sequence of SEQ ID NO: 115 and variable region of the light chain comprises the amino acid sequence of SEQ ID NO: 117, alone or anchoring the antibody on the surface of a liposome containing a toxin or an anti-cancer drug encapsulated therein.
