摘要:
Medicinal compositions for preventing and treating hemorrhagic symptoms associating abnormal blood coagulation which contain as the main active ingredient a combination of activated blood coagulation factor VII (FVIIa) with blood coagulation factor X (FX). These compositions contain no component mainly causing side effects, are highly safe and efficacious, and make it possible to easily control hemostatis. Thus, these compositions are usable in controlling the hemostatis of, for example, patients suffering from blood coagulation failure due to, for example, abnormality (including defect) in blood coagulation factors, in particular, carrying a blood coagulation factor inhibitor (antibody).

The present invention provides for a process for preparing a recombinant human thrombin. A process for preparing a recombinant human thrombin which comprises: (1) obtaining a transfectant cell producing a human prothrombin by introducing an expression vector, wherein a gene fragment coding for a human prothrombin gene is incorporated, into an animal cell; (2) purifying a human prothrombin from the culture of the transfectant cell above by an anion exchanger; (3) converting the purified human prothrombin into a human thrombin by subjecting said human prothrombin to the action of ecarin; and (4) purifying the human thrombin from the solution after treatment with ecarin by an affinity method using benzamidine and a cation exchanger, and human thrombin obtained by said process, and a CHO cell that produces human prothrombin.

摘要:
The present invention provides a fluorescent substance excellent in thermal resistance, which can be uniformly dispersed into plastic materials, and has a high fluorescence intensity even after experienced heat history in plastic forming processes. More specifically, the present invention provides a fluorescent substance containing a rare earth complex having benzophenone or benzoyl substituted with an alkyl group, a cycloalkyl group, an acyl group or an alkoxy group having a carbon number of 1 to 20 as a skeletal structure, in which a plurality of rare earth ions are coordinated with one or more types of molecules having a photosensitizing function.
摘要:
When genes encoding three kinds of proteins constituting fibrinogen, an α chain (or variant of α chain), a β chain and a γ chain (or variant of γ chain) are incorporated into an animal cell, a constitutional ratio of respective genes is such that a γ chain (and/or variant of γ chain) gene is an equal amount to a 1000-fold amount relative to an α chain (and/or variant of α chain) gene and a β chain gene and, further, by using a baculovirus P35 gene, a recombinant fibrinogen highly producing cell is prepared.

摘要:
A novel prophylactic/remedy for immunopathy is provided which is not neutralized by a neutralizing antibody to Staphylococcal enterotoxin B (SEB), known as one of superantigens, and may effectively act as a superantigen. A modified SEB having a reduced reactivity with a neutralizing antibody to SEB (anti-SEB antibody) and a prophylactic/remedy for immunopathy comprising as an active ingredient said modified SEB. The modified SEB of the present invention may be prepared with the evolutionary molecular engineering technique by introducing amino acid substitution in the amino acid sequence of SEB, especially at an epitope recognition site of the anti-SEB antibody in the amino acid sequence of SEB.
摘要:
A heterologous protein free from an inducer and a method for producing said protein are provided. A method for producing a heterologous protein which comprises the step of optionally culturing at low temperature recombinant E. coli cells expressing a heterologous protein under control of a promoter capable of inducing expression through temperature shift and then culturing at high temperature said recombinant E. coli cells in the absence of an inducer to thereby allow for expression of said heterologous protein, or the step of culturing at high temperature said recombinant E. coli cells to thereby simultaneously allow for both cell proliferation and expression of said heterologous protein, and the heterologous protein obtained by said method that is free from an inducer. Such heterologous protein may include a major mite allergen, a secretary macrophage toxin from Actinobacillus pleuropneumoniae and a surface protective antigen (SpaA) of Erysipelothrix rhusiopathiae.
