摘要: The invention relates to methods of sterilizing biologically active products, particularly therapeutic or prophylactic products and the compositions obtained thereby. The methods include obtaining a dried sample containing an amount of trehalose sufficient to render heat stability to the product and exposing the dried sample to heating conditions at a temperature and for a duration sufficient to substantially inactivate viruses, especially non-lipid encapsulated viruses. The drying methods include both ambient drying conditions and lyophilization. The heating conditions include any known in the art and cover a wide range of temperatures and heating times. The compositions obtained contain stable products and do not contain measurable infectious virus, particularly parvovirus.

摘要: Psoralen compound compositions are synthesized which have primaryamino substitutions on the 3-, 4-, 5-, and 8-positions of the psoralen, which yet permit their binding to nucleic acid of pathogens. Reaction conditions that photoactivate these psoralens result in the inactivation of pathogens which contain nucleic acid. The compounds show similar activity in test systems to 4′ and 5′ derivatives of proralen useful for inactivation of pathogens in blood products. In addition to the psoralen compositions, the invention contemplates such inactivating methods using the new psoralens.

摘要: An apparatus and method for illuminating a fluid having photosensitive material therein comprising a surface and a roller separated from the surface by a space. The space is adapted to receive a flexible container therein. The flexible container on the surface contacts the roller and the surface for translation through the space. A light source is adapted to transmit light to the space to illuminate the fluid and react with the photosensitive material as the flexible container translates through the space.

摘要: The present disclosure relates to a method for attenuating an influenza virus, an attenuated influenza virus strain and use thereof, and belongs to the technical field of attenuated vaccines. In the present disclosure, the method includes the following steps: conducting synonymous mutation on an overlap of an M2 gene and an M1 gene in an M gene of an influenza A virus, while ensuring integrity and invariance of an amino acid sequence encoded by the M1 gene; conducting mutation into termination codon and deletion of partial nucleotide sequence in a transmembrane domain of the M2 gene, and rescuing an attenuated influenza virus strain using a reverse genetic system.

摘要: Embodiments disclosed herein provide nucleic acid constructs and methods of use thereof that induce a live cell to give off sub-samples of the cell's cytosolic content. The tem “cell” as used herein may be any cell type. In certain example embodiments, the cells are mammalian cells. The sampling can be general or can be targeted to a particular class of molecules or to specific types of molecules. The constructs facilitate generation of a read-out for high-throughput screens by combining engineered export with simple bulk sample and sample processing. Live cell sampling enables time course measurements and expands, for example, the applicability of transcriptional profiles obtained by single cell gene expression analysis.

摘要: Reported herein are presumptively de-attenuating mutations that are useful, either individually or in combinations that may include other known mutations, in producing recombinant strains of human respiratory syncytial virus (RSV) exhibiting attenuation phenotypes. Also described herein is a novel RSV construct, Min_L-NPM2-1(N88K)L, which exhibits an attenuated phenotype, is stable and is as immunogenic as wild type RSV. The recombinant RSV strains described here are suitable for use as live-attenuated RSV vaccines. Exemplary vaccine candidates are described. Also provided are polynucleotide sequences capable of encoding the described viruses, as well as methods for producing and using the viruses.
