摘要:
F gene-deficient virus virions are successfully recovered by using an F gene-deficient Sendai virus genomic cDNA. Further, F gene-deficient infectious viral particles are successfully constructed by using F-expressing cells as helper cells. Also, F gene and HN gene-deficient virus virions are successfully recovered by using a virus genomic cDNA deficient in both F gene and HN gene. Further, F gene and HN gene-deficient infectious viral particles are successfully produced by using F- and HN-expressing cells as helper cells. A virus deficient in F gene and HN gene and having F protein is constructed by using F-expressing cells as helper cells. In addition, M gene-deficient infectious virus particles were produced using helper cells expressing M protein. From cells infected with M gene-deficient viruses, release of virus-like particles was inhibited. Further, a VSV-G pseudo type virus is successfully constructed by using VSV-G-expressing cells. Techniques for constructing these deficient viruses contribute to the development of vectors of Paramyxoviridae usable in gene therapy.
摘要:
A functional RNP containing negative-strand single-stranded RNA derived from Sendai virus, which has been modified so as not to express at least one envelope protein, has been successfully prepared. An RNP comprising a foreign gene is prepared and inserted into a cell with the use of a cationic liposome, thereby successfully expressing the foreign gene.
摘要:
The position adjusting apparatus comprises a stationary frame, first and second movable stages respectively, disposed on X and Y axes intersecting at right angles, a plurality of dynamic type electro-mechanical transducers mounted on the axial ends of each movable stage, a first resilient supporting member for mounting the first movable stage to be movable in the direction of X axis, a second resilient supporting member mounted on the first movable stage forming the second movable stage in the direction of the Y axis, and a platform mounted on the second movable stage for supporting an object whose position is to be adjusted.
