  • Patent number: 9005910
    Abstract: The purpose is to produce, with high reproducibility, a complex of labeled probes and a carrier, said complex being to be used for detecting and measuring a target substance to be measured with high sensitivity and high stability. The means for accomplishing the purpose is that a label is bound to a probe-water soluble carrier conjugate using specific binding of an avidin compound such as avidin, streptavidin, etc. to biotin, and the binding of the avidin compound to the probe is performed before the binding to the carrier. Namely, after conjugating the avidin compound to a substance which is capable of binding to the target substance, the conjugate is bound to a high-molecule water-soluble carrier to produce a complex of the avidinized probes and the water-soluble carrier. Then the complex of the avidinized probes and the water-soluble carrier is mixed with a biotinylated label.

  • Publication number: 20140050693
    Abstract: Increased in vivo and/or in vitro stability is imparted to a biologically active protein by fusing to an amino acid sequence consisting of at least about 100 amino acid residues, which consist essentially of Alanine, Serine and Proline, which form a random coil conformation. Specific examples are described. Also described are related nucleic acids, vectors and cells encoding such amino acids; compositions of biologically active proteins fused to a random coil domain, and methods of making and using the compounds and compositions of the invention.

  • Publication number: 20140030702
    Abstract: The immunogenicity of the influenza virus hemagglutinin (HA) molecule may be increased by substitutions of amino acids in the HA sequence. The substitution of specific HA residues, such as asparagine at position 223 of H5 HA, increase the sensitivity of the hemagglutinin inhibition (HI) assay by altering receptor specificity and/or antibody-antigen binding. HA molecules containing such substitutions will be useful in the development of diagnostic reference viruses and improved influenza vaccines.

  • Publication number: 20130302360
    Abstract: Problem to be Solved: The present invention provides a novel mucosal adjuvant. Solution: The present invention provides a mucosal adjuvant composition containing at least a composition comprising molecules having a molecular weight in a range of 100 to 300 kDa obtained from cells or culture fluid of Bordetella bronchiseptica. Administration of the mucosal adjuvant composition to a non-human animal at a surface of the mucous membrane can enhance immunity at the surface of mucous membrane. Therefore preventive effects against trans-mucosal infection can be increased by administering an inactivated vaccine against trans-mucosal infection and the mucosal adjuvant composition to a non-human animal at a surface of mucous membrane. The present invention is effective for preventing trans-mucosal infections, including one or more infections of e.g., canine parainfluenza, canine adenovirus, canine coronavirus, canine parvovirus, canine distemper virus, canine herpesvirus, reovirus and pneumovirus.
