A sample scraping method and a sample scraping device capable of efficiently scraping and collecting a biological tissue section without waste while suppressing contamination is provided. In a sample scraping method for scraping and collecting a biological tissue section held on a slide, the FFPE section held on the slide is heated, and the heated FFPE section is scraped by a blade such that the FFPE section that has been scraped off and remains on the blade is collected in a container.

Sample scraping method and sample scraping device

A cell processing apparatus includes a storage container that contains liquid L including a biological sample; a filter that prevents a first cell Cin the biological sample from passing and allows a second cell Chaving a smaller diameter than that of the first cell Cto pass; and a filtration cylinder for separating, in the storage container and via the filter, the liquid L into a first liquid Lmainly including the first cell Cand a second liquid Lmainly including the second cell C. A measurement target cell filtered by the filter among other cells can be easily collected.

A cell processing apparatusof the present invention includes a storage containerthat can contain liquid L including a biological sample; a filterthat prevents a first cell Cin the biological sample from passing therethrough and that allows a second cell Chaving a smaller diameter than that of the first cell Cto pass therethrough; and a filtration cylinderfor separating, in the storage containerand via the filter, the liquid L into a first liquid Lmainly including the first cell Cand a second liquid Lmainly including the second cell C. A measurement target cell discriminated by the filter from the other cells can be easily collected.

A method of activating an antigen is herein described. The method comprises providing an antigen activation solution and contacting the cell with the solution to activate the antigen. A method of detecting a cell fixed by a nonbridging fixation solution is also described. The method comprises providing an antigen activation solution, contacting the cell with the solution, immunostaining the cell, and detecting the stained cell. The solution used for these methods comprises an agent for breaking a hydrogen bond, and is also described herein.
