  • Publication number: 20130041137
    Abstract: This invention is intended to isolate and identify a vWF-specific cleaving protease. The vWF-specific cleaving protease cleaves a bond between residues Tyr 842 and Met 843 of vWF and comprises a polypeptide chain having Leu-Leu-Val-Ala-Val (SEQ ID NO: 1) as a partial sequence, and more preferably comprises a polypeptide chain having the partial N-terminal amino acid sequence of a mature protein, Ala-Ala-Gly-Gly-Ile-Leu-His-Leu-Glu-Leu-Leu-Val-Ala-Val (SEQ ID NO: 2), and having a molecular weight of 105 to 160 kDa in SDS-PAGE under reducing or non-reducing conditions. Isolation and identification of this vWF-specific cleaving protease have led to the possibility of replacement therapy for patients having diseases resulting from a deficiency of the protease, such as thrombotic thrombocytopenic purpura.

  • Publication number: 20110314158
    Abstract: An application allocation system is provided, by which a supposed execution environment can be obtained when an application is actually executed even in a case where the computer resources of the allocation destination dynamically varies. The allocation originating server obtains an execution condition of each component as application information, determines a component group having possibility to be allocated as an allocation candidate component group, generates a resource subscription request indicating an execution condition of the allocation candidate component group and transmits it to each allocation candidate server, and determines the allocation destination server of each component from the allocation candidate component group.

  • Patent number: 7635577
    Abstract: A genetic recombinant human thrombin is provided. Human thrombin is efficiently prepared by the genetic engineering technique comprising the steps: (1) culturing a transfectant animal cell transfected with an expression vector in which a gene encoding human prethrombin is incorporated to the downstream of a promoter so as to produce and accumulate prethrombin in culture supernatant and recovering the produced human prethrombin; (2) treating a solution containing human prethrombin recovered in step (1) with ecarin so as to convert human prethrombin into human thrombin; and (3) purifying the solution obtained after the above activation process to obtain purified human thrombin. The present invention allows for provision of human thrombin in a large scale in a safe and economical manner due to exclusion of blood-derived components.
