Disclosed are a mutant transposon vector and a method for introducing a foreign gene into a cell. A mutant transposon vector having a nucleic acid fragment inserted therein, the nucleic acid fragment having the properties (i) and (ii) or the properties (i) to (iii) below; a foreign gene-expressing cell which is prepared by introducing the mutant transposon vector into the chromosomal DNA of an established cell or a cell capable of being individuated and then additionally introducing a foreign gene-expressing cassette into a recombinant system (e.g., Cre-Lox system); a recombinant animal created by using the cell (in the case where the cell capable of being individuated is used); and a method for producing a foreign protein from the cell or the recombinant animal: (i) comprising a 5'-TIR sequence and a 3'-TIR sequence of transposon gene; (ii) having a sequence at which a recombination reaction occurs inserted between at least one set of DR regions of two sets of DR regions present in a 5'-TIR sequence or a 3'-TIR sequence of transposon gene; and (iii) having a restriction recognition site or a foreign gene-expressing cassette inserted between a 5'-TIR sequence and a 3'-TIR sequence of transposon gene.
摘要:
The present invention provides a method for enhancing the immunogenicity using a microneedle device capable of enhancing the immunogenicity of an influenza vaccine. According to the method for enhancing the immunogenicity using the present microneedle device, a microneedle device having microneedles made of polylactic acid, coated with an influenza vaccine composed of an antigen having type A strain (H1N1), type A strain (H3N2), and type B strain as active ingredients is brought into direct contact with the skin so as to transcutaneously administer the aforementioned influenza vaccine. After the transcutaneous administration, lauryl alcohol is applied to the site of the skin where the microneedle device has been brought into direct contact.
摘要:
It is intended to provide a novel agent for improving neurotransmission failure. In a preferable case, an agent for improving neurotransmission failure which contains, as the major active ingredient(s), a selenocysteine-containing protein typified by selenoprotein P, a C-terminal peptide of this protein or such peptides. This agent is appropriate in improving neurotransmission failure diseases caused by various factors.
摘要:
A novel adjuvant composition is provided that is excellent in safety and convenience as compared to the conventional adjuvant such as Alum. An adjuvant composition comprising citrullines, which are water soluble substance present in the living body, and/or a salt thereof; a vaccine composition comprising said adjuvant composition and an antigen; a process for preparing said adjuvant composition and said vaccine composition; and a method for administering said adjuvant composition and said vaccine composition are provided.
摘要:
