摘要:
A recombinant ecarin protein that specifically activates prothrombin, said protein being efficiently prepared by the genetic engineering technique comprising the steps: (1) culturing a transformant microorganism or animal cell transformed with an expression vector in which a gene encoding ecarin is incorporated to the downstream of a promoter so as to produce and accumulate ecarin in culture supernatant or within said transformant and recovering the produced ecarin; and (2) purifying a solution containing the recovered ecarin to obtain purified ecarin. The present invention allows for production of recombinant ecarin on an industrial scale.

摘要:
A human polyclonal antibody having an antibacterial and/or antiviral activity with a desired titer and a wide spectrum; and human polyclonal antibody composition for preventing and treating infections which contain this antibody. The human polyclonal antibody composition for preventing or treating infections contain the human polyclonal antibody which is obtained by administering as immunogen a bacterium and/or a virus or a component of the bacterium and/or the virus to a non-human animal having a human antibody gene locus and has an antibody titer against the bacterium and/or the virus exceeding that of human pool plasma.
摘要:
A novel selenocysteine-containing protein is provided which is a substantial entity having an enzymatic activity, typically an activity to reduce peroxide phospholipids. There are provided a gene consisting of a coding sequence for a protein not containing selenocysteine in which the codon for selenocysteine is introduced at a desired position and a selenocysteine insertion sequence resided at the 3'-end of said coding sequence and a protein expressed therefrom, typically a selenocysteine-containing protein having an activity to reduce peroxide phospholipids which is prepared by introducing selenocysteine into albumin and as well as a gene encoding said protein. A novel anti-oxidative substance is provided which can be applied for prevention of worsening, prophylaxis or treatment of various diseases associated with oxidative stress.
摘要:
A novel medicament for treating neurodegenerative diseases, especially for ameliorating dyskinesia, comprising as an active ingredient selenoprotein P and/or a peptide fragment or a series of peptide fragments derived from said protein is provided. The novel medicament for treating neurodegenerative diseases, especially for ameliorating dyskinesia, according to the present invention is suitably applicable to diseases with decrease in motor function.
摘要:
Antisense oligonucleotides are provided which are complementary to at least a portion of HCV RNA and specifically hybridizable therewith. These oligonucleotides can be administered to inhibit the replication of Hepatitis C virus in vivo or in vitro and to treat Hepatitis C virus-associated disease. These compounds can be used either prophylactically or therapeutically to reduce the severity of diseases associated with Hepatitis C virus.
