  • Publication number: 20210100884
    Abstract: A novel vaccine that can induce sufficiently high cell-mediated immunity is disclosed. The vaccine of the present invention contains, as an effective component, a polypeptide comprising a tandem repeat structure in which an MHC class I epitope region derived from an antigen protein and a spacer sequence are linked to each other alternately and repeatedly at least three times, or a recombinant vector which comprises a polynucleotide encoding said polypeptide and is capable of expressing said polypeptide in vivo. The spacer sequence is, for example, a sequence generated as an amino acid sequence inevitably encoded by a single base sequence which is designed such that the MHC class I epitope region derived from the antigen protein, an MHC class II epitope region derived from the antigen protein, and at least one higher-order-structure-stabilizing region are encoded by different reading frames in said single base sequence.

  • Patent number: 10233099
    Abstract: Disclosed herein is a radioactive cesium decontaminator, a method of producing a radioactive cesium decontaminator, and a method of removing radioactive cesium using the decontaminator. The radioactive cesium decontaminator is formed by agglomeration of primary particles. The primary particles have a magnetic particle as a core portion, a coating layer made of an organic material coating the magnetic particle, and a capturing compound made of ferrocyanide material formed on the coating layer. A cumulative diameter D50 of the decontaminator is in a range of from 2.0 ?m to 50 ?m, and a value of a cumulative diameter distribution (D90?D10)/D50 is less than 6. The decontaminator is made by adding a ferrocyanide aqueous solution and an aqueous solution containing at least one transition metal into a suspension liquid containing a precursor formed by magnetic particles coated with organic monomer or polymer while applying a strong shear force.
