In order to conduct gene expression analysis of a number of genes in a number of cells, it has been necessary to separate cells, extract genes therefrom, amplify nucleic acids, and perform sequence analysis. However, separation of cells imposes damages on the cells, and it requires the use of an expensive system. Gene expression analysis in each cell can be carried out with high accuracy by arranging a pair of structures comprising a cell trapping section and a nucleic acid trapping section in a vertical direction to extract individual genes in relevant cells, synthesizing cDNA in the nucleic acid trapping section, amplifying nucleic acids, and analyzing the sequences using a next-generation sequencer.

In order to interpret an arbitrary sequence region in many genes in many cells, it is necessary to degrade a nucleic acid into fragments and introduce a sequence that is different from one cell to another into each of the fragments. However, in the conventional configuration for analyzing many cells, there has been a problem that mixing of the degraded fragments among areas occurs before a tag sequence unique for each of the areas is introduced. The present invention provides a system for capturing a nucleic acid extracted from a cell in each of plural areas on a substrate and synthesizing a complementary DNA (cDNA) of the nucleic acid for each of the areas, wherein the system also includes a means for immediately introducing a tag sequence unique for each of the areas to the reaction product.

The present invention aims to provide a data analysis apparatus capable of clustering appropriately even when there is an exceptional datum resulted from an experimental error and the like. In the data analysis apparatus according to the invention, a cluster range parameter for stretching a cluster boundary is determined in advance according to the range of an experimental error which an experimental error datum describes. In the process of clustering, an exceptional datum which does not belong to any cluster is determined to belong to a cluster when an area at a distance determined by the cluster range parameter from the exceptional datum is contained in the cluster, and the exceptional datum is determined to form an independent cluster when even the area at the distance is not contained in any cluster (see FIG. 7).

摘要:
The present invention optically obtains characteristic values of a plurality of biological samples from a specimen; compares the characteristic values with examination information associated with the same specimen obtained in advance; and calculates an indicator to determine, based on a result of the comparison, whether a process is continued to genetic analysis of the biological samples or a re-preparation of samples from the same specimen is performed. By this method, it is possible to achieve more reliable biomarker detection by ensuring validity through appropriate selection of test samples while reducing cost, effort, and time for analysis in single cell analysis or analysis of a group of a small number of cells.
摘要:
Spectral data such as a CARS spectrum of a sample is acquired at high speed by reducing the amount of data. During scan by emission light focused and emitted onto the sample, the exposed state of a detection unit of a spectroscope that divides light generated from the sample is continued, thereby acquiring spectral data obtained by summing spectra generated at a plurality of positions in the sample.
