Problems solved by technology

It has been reported to use the mouse cell surface markers CD71 and Ter119 for dual-parameter labeling to study mouse erythroid cells, but this method cannot distinguish reticulocytes from mature erythrocytes, and the antibody price is generally high, so using both CD71 and Ter119 Antibodies make the detection cost high, which is not conducive to popularization and application

Abstract

The invention discloses a method for analyzing and evaluating the erythropoiesis function of mouse marrow through a flow cytometry. According to the method, mouse marrow cells are subjected to dyeing incubation with thiazole orange, rat IgG and APC Rat Anti-mouse Ter119. Incubation sequence is that firstly, the mouse marrow cells and thiazole orange are incubated for appropriate time, centrifugation and supernatant abandoning are conducted, then, rat IgG is added to be incubated for appropriate time, and APC Rat Anti-mouse Ter119 is added to be incubated for appropriate time. Finally, PBS is added, the proportions of mature erythrocytes, reticulocyte, normoblast and proerythroblast in all cells of the mouse marrow are quantitatively analyzed on the flow cytometry, and therefore the erythropoiesis function of the mouse marrow is analyzed and evaluated. The method is quick, accurate, simple, easy to practice, low in cost and beneficial to application and popularization.

Description

technical field [0001] The invention relates to the technical field of flow cytometry, in particular to a method for analyzing and evaluating mouse bone marrow erythropoietic function by using flow cytometry. Background technique [0002] Mature erythrocytes are the most abundant type of blood cells in the body's blood, and are the most important medium for the body to transport oxygen through the blood. In recent years, studies have found that erythrocytes are also important immune cells of the body, and play an important role in fighting diseases and tumors. Mature erythrocytes are derived from erythroid progenitor cells in the bone marrow erythroid system through the gradual differentiation and development of proerythrocytes, immature erythrocytes and reticulocytes. Therefore, detecting the proportion of red blood cells in each period to analyze and evaluate the bone marrow erythropoietic function is of great significance for further exploring the role of red blood cells ...
