  • Patent number: 6806049
    Abstract: In gene expression frequency analysis, a vector primer to which each cDNA is ligated is formed by synthesizing the cDNA from each mRNA using by a vector primer having a poly(T) sequence; each cDNA sequence is converted to a tag on the vector primer; a concatemer is formed by ligating the obtained tags via a sequence that enables recognition of ends of the tags; and the nucleotide sequence of the concatemer is analyzed.

  • Publication number: 20030180801
    Abstract: Each gene in a group comprising many genes is cloned into an expression vector so that its gene product should be expressed as a fusion protein with a protein emitting self-fluorescence to construct a gene expression library. The gene expression library is introduced into cells of two groups to express the fusion proteins in the cells, and only one cell group is stimulated by a drug or the like. Then, cells in which the fusion proteins are localized in the nuclei or their nuclei are isolated from cells of the two groups, respectively. By comparing these cells, genes coding for proteins that are transported into the nuclei specifically in response to a certain stimulus when the stimulus is applied to the cells are retrieved.

  • Patent number: 6409141
    Abstract: A flow cell 2, a composite lens 15, and first to third detectors 16 to 18 are arranged in this sequence in the light pathway of light emitted from a laser light source 1. The composite lens 15 is configured by a convex lens 15a, and lens elements 15b and 15c. These lenses have different focal lengths. When the posture of the composite lens is correct, light impinging on the convex lens forms an image on the first detector. Therefore, the positioning of the composite lens is enabled. When particles in the flow cell are irradiated with laser light, forward scatter is produced. Forward small angle scatter having a small scattering angle impinges on the first lens element 15b to be collected thereby, and is then received by the second detector 17. Forward large angle scatter having a large scattering angle impinges on the second lens element 15c in the outermost periphery to be collected thereby, and is then received by the third detector 18 which is remotest from the composite lens.
