摘要:
A protein, a DNA encoding this protein and an antibody recognizing this protein. Use of these substances makes it possible to provide a method of judging diseases relating to the novel insulin-like growth factor-binding protein, and diagnostics, preventives and remedies for diseases relating to the above-described protein.

It is intended to provide a cell having an RNA, which inhibits the function of an enzyme catalyzing the reaction of converting GDP-mannose into GDP-4-keto,6-deoxy-GDP mannose, transferred thereinto; a method of producing a glycoprotein composition by using this cell; a cell having an RNA which inhibits the function of an enzyme participating in the sugar chain modification of the binding, via a-bond, of the 1-position of fucose to the 6-position of N-acetylglucosamine at the reducing end of an N-glycoside bond type complex sugar chain, an RNA which inhibits the function of an enzyme protein participating in the intracellular synthesis of a sugar nucleotide GDP-fucose, or an RNA inhibiting the function of a protein participating in the intracellular transport of a sugar nucleotide GDP-fucose into the Golgi body, transferred thereinto; a method of producing a glycoprotein composition by using this cell; and so on.
摘要:
A method of obtaining a solution having an activity of inducing the differentiation of embryo stem cells into ectodermal cells or ectoderm-origin cells which involves the step of culturing stroma cells with the use of a liquid medium containing a polyanion compound and then recovering the liquid medium; a solution having an activity of inducing the differentiation of embryo stem cells into ectodermal cells or ectoderm-origin cells which is obtained by using the above method; and an inducer for the differentiation of embryo stem cells into ectodermal cells or ectoderm-origin cells.
摘要:
Cells wherein the genome has been modified so that the activity of an enzyme relating to the sugar chain modification of binding the 1-position of fucose to the 6-position of a N-acetylglucosamine at the reducing end of a complex N-glycoside linked sugar chain via an α-bond is lowered, compared with the activity in the parent strain cells, or deleted; and a process for producing an antibody composition using these cells.

摘要:
It is intended to provide a process for producing an antithrombin III composition comprising a genetically modified antithrombin III molecule having an N-glycoside-binding complex sugar chain, which has an N-glycoside-binding complex sugar chain having no fucose attached to N-acetylglucosamine at the reducing end of the sugar chain.
摘要:
It is intended to provide a cell capable of regulating the sugar chain structure of a glycoprotein which is a protein product thereof, namely, a cell carrying a knockout genome gene of an enzyme which catalyzes a dehydration reaction of converting GDP-mannose into GDP-4-keto,6-deoxy-GDP mannose; a process for producing a glycoprotein by using the cell; a glycoprotein produced by this process; and its use.
摘要:
A process for producing an antibody composition with the use of cells characterized by using cells tolerant to a lectin recognizing a sugar chain structure in which an α-bond is formed between the 6-position of N-acetylglucosamine at the reducing end of an N-glycoside bond-type complex sugar chain and the 1-position of fucose; and cell usable in this process.
摘要:
Attempts have been made to develop host cells capable of producing glycoprotein compositions such as antibody compositions useful in drug discovery. It is intended to provide a cell having been neutralized to a serum-free medium and carrying a knockout genome gene of an enzyme which participates in a sugar chain modification whereby fucose is attached via an alpha-bond at the 1-position to the 6-position of N-acetylglucosamine at the reducing end of an N-glycoside-binding complex sugar chain; and a process for producing a glycoprotein composition with the use of this cell.
