Verfahren zur Durchflusszytometrie-Unterscheidung der Erythroblasten von anderen Zellen
摘要
A method which comprises using a specified dye taken up by erythrocytic nucleated cells so that their nuclei are stained and can be readily differentiated from other cells by measurement with a flow cytometer is disclosed. The method for differentiating erythroblasts from other cells relies basically upon flow cytometry by two-step staining that uses a first fluid that is an acidic hypotensive fluorescent dye solution and a second fluid that is a solution that changes the osmorality and pH of the first fluid. The first fluid further contains a fluorescent dye that diffuses into erythroblasts to specifically stain their nuclei, and a group of erythroblasts is separated from other cell groups on the two-dimensional plot constructed with the flow cytometer, whereby the results of erythroblast differentiation are computed.
