摘要:
A recombinant avian infectious coryza vaccine and a process for preparing the same are provided. A process for preparing a recombinant avian infectious coryza vaccine which comprises step of constructing E. coli that may produce as an inclusion body a fusion peptide consisting of peptides derived from outer-membrane protein of Avibacterium paragarinarum serotype A and serotype C, step of culturing said E. coli and colleting and purifying inclusion body from culture, and step of preparing a preparation comprising said purified inclusion body, and an avian infectious coryza vaccine comprising as an active ingredient the fusion peptide. A linker sequence may be inserted between the respective peptides comprising the fusion peptide. For the peptide derived from the serotypes A and C, an amino acid sequence region of Region 2 or its vicinity responsible for protection from infection may be used.

A method and a kit for detecting an antibody to Avibacterium paragallinarum are provided. A method for detecting an antibody to Avibacterium paragallinarum which comprises detecting an antibody induced by an outer-membrane protein of Avibacterium paragallinarum serotype A and/or serotype C by ELISA with a solid phase to which a peptide consisting of an amino acid sequence of non-homologous region of said outer-membrane protein or a portion thereof is immobilized, and a detection kit used for said method.

A variant of Erysipelothrix rhusiopathiae surface protective antigen SpaA protein or of a shortened form of SpaA (ΔSpaA) in which a portion of SpaA protein is deleted for protection from Erysipelothrix rhusiopathiae infection and a process for preparing the same are provided. Introduction of amino acid substitution at a specific site in the amino acid sequence of SpaA or ΔSpaA protein provides a variant of SpaA or ΔSpaA protein which is immunogenic and is expressed in E. coli as inclusion bodies. The variant of SpaA or ΔSpaA protein of the present invention may easily be recovered and purified since it is expressed in E. coli as inclusion bodies.
摘要:
By incorporating (A) a saturated hydrocarbon polymer having more than one alkenyl group capable of being hydrosilylated in each molecule and having a molecular weight of 2,000 to 50,000, (B) a component comprising a compound containing more than two silicon atom-bound hydrogen atoms, on average, in each molecule, (C) a compound having, within the molecule, one alkenyl group capable of being hydrosilylated, (D) a compound having, within the molecule, at least two alkenyl groups capable of being hydrosilylated and having a molecular weight less than 2,000, and (E) a hydrosilylation catalyst, a composition having good mechanical characteristics, a high gel fraction and a small heating loss can be obtained. As a result, the invention can provide a composition to secure the uniformity within a wide range of selection not depending on its viscosity, because it is markedly relaxed the restriction on SiH-containing compounds that are curing agents possibly becoming a cause of said insufficient curing.

A wire electric discharge machining apparatus can select a split guide formed from a pair of guide pieces, or an unsplittable dice guide, as an upper wire guide. An upper wire guide assembly includes a housing configured to selectively store the split guide or an adapter that the dice guide fitted into, and an actuator configured to move at least one of the pair of guide pieces. When the split guide is selected, a guide pipe configured to form a fluid jet can be moved downward through the upper wire guide assembly. When the dice guide is selected, an AWT jet nozzle configured to form a fluid jet can be attached to the adapter. Further, a jacket can be attached to the housing, the jacket having a fluid inlet configured to introduce fluid to be supplied to the AWT jet nozzle.
