Patent number: 11660596Abstract: The present invention provides a medical analysis device and a cell analysis method, which can capture specific cells such as many types of cancer cells including cancer cells not expressing EpCAM and stem cells. Provided is a medical analysis device including a well portion, the well portion having a hydrophilic silane compound layer formed at least partly on the inner surface thereof.Type: GrantFiled: March 25, 2020Date of Patent: May 30, 2023Assignees: SUMITOMO RUBBER INDUSTRIES, LTD., YAMAGATA UNIVERSITYInventors: Yasuhisa Minagawa, Masaru Tanaka, Haruka Emura, Kazuki Suto

Patent number: 11614440Abstract: Provided are specific cell-fractionating and -capturing methods which can fractionate and capture, respectively, specific cells (e.g., many types of cancer cells, including cancer cells not expressing EpCAM, or peripheral blood stem cells). Included is a method for fractionating specific cells present in blood or biological fluid, the method including fractionating the blood or biological fluid by centrifugation to collect the specific cells in the blood or biological fluid, the centrifugation being carried out using a container having a low protein adsorbing layer at least partially formed on the inner surface thereof.Type: GrantFiled: December 27, 2019Date of Patent: March 28, 2023Assignees: SUMITOMO RUBBER INDUSTRIES, LTD., YAMAGATA UNIVERSITYInventors: Yasuhisa Minagawa, Masaru Tanaka, Haruka Emura, Kazuki Suto

Patent number: 11573232Abstract: The present invention provides a method for capturing specific cells (e.g. many types of cancer cells, including cancer cells not expressing EpCAM), and a method for analysis of specific cells involving the method. Included is a method for capturing specific cells present in blood or biological fluid, the method including: agglutinating blood cells in sampled blood or biological fluid; centrifuging the resulting blood or biological fluid; and then capturing specific cells therefrom onto a hydrophilic polymer layer.Type: GrantFiled: January 16, 2019Date of Patent: February 7, 2023Assignees: SUMITOMO RUBBER INDUSTRIES, LTD., YAMAGATA UNIVERSITYInventors: Yasuhisa Minagawa, Masaru Tanaka, Takashi Hoshiba, Haruka Emura
