Abstract:
The invention relates, in part, to a method of producing silica vesicles including under controlled conditions to thereby heavily influence the morphology and characteristics of the vesicles. The vesicles are shown to be effective as delivery agents for chemical and biological agents. They are also shown to be useful in methods of treatment and as components of an immunogenic composition.
Abstract:
Described herein are flavivirus virus-like particles (VLPs) that display on their surfaces antigenic flavivirus proteins. Also described are methods of making and using these VLPs.
Abstract:
The present invention provides methods of reducing the levels of a titratable selectable pressure required, the number of amplification cycles, and the time taken to generate protein expressing cell lines by altering the codons of the desired open-reading-frames. Through the use of codon adaptation for this purpose the methods of the invention consistently provide sufficient yields in faster time frames saving many weeks in cell line development activities. Furthermore the methods of the invention also generate cell lines with lower concentrations of selection and amplification agent than previously achievable. Accordingly lower levels of selection and amplification marker in the final cells lines are observed.
Abstract:
The invention concerns a process for disintegrating any biologically active nucleic acid in a biological material. According to the invention, a biologically active material is exposed one or a plurality of times to a laser beam in order essentially to disintegrate the entire biologically active nucleic acid in this biological material, whilst the biological integrity and activity of the biological material are retained.
Abstract:
본 발명은 식물 유래 돼지 열병 항원 pmE2 단백질 생산용 재조합 벡터, 상기 재조합 벡터로 형질전환된 식물체, 상기 식물체에서 발현된 식물 유래 돼지 열병 항원 pmE2 단백질 및 이의 용도에 관한 것이다. 본 발명에 따른 돼지 열병 바이러스의 GP55 단백질을 코딩하는 폴리뉴클레오티드; 및 셀룰로오즈 결합 도메인 단백질을 코딩하는 폴리뉴클레오티드를 포함하는 재조합 벡터; 및 상기 재조합 벡터로 형질전환된 식물체를 이용 시, 식물 유래 돼지 열병 항원 pmE2 단백질을 고효율로 생산할 수 있고, 다른 생산 방법에 비해 안전성 및 안정성이 있는 장점이 있다. 또한, 상기 식물 유래 돼지 열병 항원 단백질 pmE2는 셀룰로오즈 결합 도메인(cellulose-binding domain: CBD) 단백질을 포함하기 때문에, 돼지 열병 바이러스 노출 경로 및 항체 생성 경로를 판별하는데 있어 효과적인 마커로서 유용하게 이용될 수 있다.
Abstract:
It is disclosed herein that viruses coated in silica retain infectivity and the capacity to induce an immune response in an infected host. In addition, silicifled virus is remarkably resistant to desiccation. Provided herein are methods of inducing a virus-specific immune response in a subject by administering to the subject an effective amount of silicified virus or silicified virus particles. Methods of enhancing a virus-specific cell-mediated immune response (such as aT cell-mediated immune response) in a subject by administering to the subject a silicified virus or silicified virus particles are also described herein. Further provided are immunogenic compositions comprising silicified virus or silicified virus particles, such as compositions useful as vaccines. The immunogenic compositions include a pharmaceutically acceptable carrier and/or an adjuvant.
Abstract:
The present invention relates to immunogenic compositions and vaccines of flavivirus. In particular, the present invention relates to improved Dengue vaccines and the design and making of such vaccines that enhance immunogenicity of the vaccine. The vaccines and immunogenic compositions of the present invention relate to mixed head bivalent flagellin-dengue antigen fusion proteins which can be combined with other bivalent dengue antigen fusion proteins or monovalent dengue antigen fusion proteins to produce multivalent vaccine including tetravalent vaccines.
Abstract:
Embodiments of the present invention generally provide an inactivated chimeric virus vaccine and/or immunogenic composition for the treatment or prevention of viral infection. Further, various other mbodiments of the present invention generally relate to methods of preventing and treating virus infection in such animals with the inactivated vaccine and/or immunogenic composition. Other embodiments comprise methods of preparing a vaccine or immunogenic composition for the treatment or prevention of viral infection in such animals.
Abstract:
A recombinant baculovirus comprises a cDNA coding for all or part of antigenic envelope protein E and/or a cDNA coding for all or part of non-structural antigenic protein NS1 of a virus belonging to Flaviviridae or a virus related thereto, and is inserted into the polyhedrin gene between nucleotide + 35 and nucleotide + 170 with the A of the polyhedrin's modified start codon having number + 1. Polypeptides obtained by means of this baculovirus, and the diagnostic and therapeutical uses thereof, are also described.
