  • Patent number: 12282000
    Abstract: The present invention aims to provide a biological sample analysis device which achieves an improvement in accuracy of an analysis result, a reduction in reagent cost, and shortening of a required time. The biological sample analysis device according to the present invention compares first measurement data acquired by measuring a biological sample and second measurement data acquired by measuring a reference sample and determines that when the difference between the two exceeds a threshold value, it is necessary to remeasure the reference sample before remeasuring the biological sample and reacquire a reference value (refer to FIG. 3A).

  • Publication number: 20250067706
    Abstract: An object of the disclosure is to provide an electrophoresis system capable of suppressing recurrence of a carry-over as a result of washing of a capillary. The electrophoresis system according to the disclosure is configured to cause the sample stage to reduce the carry-over which is caused by the sample remaining in the washing container after introduction of the sample into a first capillary out of a plurality of capillaries, and influences analysis of the sample using a second capillary out of a plurality of capillaries (see FIG. 5).

  • Patent number: 11644438
    Abstract: A capillary cartridge achieves both improvement of attachability and improvement of heat dissipation performance for realizing short-time analysis. A heat dissipation body is provided between a capillary having a detection unit provided in a part thereof and a plate-like support body that supports the capillary, and temperature increase inside the capillary is suppressed by the heat dissipation body, and thereby, electrophoresis can be performed under a high voltage application condition where the amount of heat increases and analysis time is reduced. In addition, it is possible to redress complexity of an operation by reducing a fixing place at the time of attachment to only a detection unit and an electrode holder by using an integration structure in which the capillary, the supporting body, and the heat radiating body are integrated.

    Abstract: A genotype analysis device includes an electrophoresis device and a data analysis device. A mobility model management unit including an environment information receiving unit, a prediction model storage unit, and a mobility prediction unit is provided in an STR analysis unit of the data analysis device. The mobility prediction unit generates a prediction model for predicting a correction amount of a standard base length of an allele, based upon an environmental condition at the time of electrophoresis received by the environmental information receiving unit and an electrophoresis result of an allelic ladder. A base length of the allele is corrected from the environmental condition without using the allelic ladder by using the prediction model.
