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.

The human polyclonal antibody composition for preventing or treating infections contain the human polyclonal antibody which is obtained by administering as immunogen a bacterium and/or a virus or a component of the bacterium and/or the virus to a non-human animal having a human antibody gene locus and has an antibody titer against the bacterium and/or the virus exceeding that of human pool plasma.
摘要:
It is intended to provide an antibody showing a selective immunoreactivity for ADAMTS-13 and employ this antibody in epitope analysis or diagnosis of an ADAMTS-13 autoantibody-positive patient. Moreover, it is intended to provide a process for producing a modified ADAMTS-13 molecule having a partial deletion aiming at the application thereof to drugs and use thereof. Namely, an antibody specific for ADAMTS-13 which can be obtained from a warm-blooded animal immunologically sensitized with a polypeptide containing the whole ADAMTS-13 amino acid sequence or a part thereof; a process for producing an antibody involving the step of immunologically sensitizing a warm-blooded animal with a polypeptide containing the whole ADAMTS-13 amino acid sequence or a part thereof; use of the above-described antibody involving a method of detecting ADAMTS-13 and a purification method; and a modified ADAMTS-13 molecule having a partial deletion.
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:
