Problems solved by technology

[0006] Second, the glue used for sticking is toxic and can adversely affect isolated blood cells
It cannot be completely removed even by baking or washing
Moreover, washing and baking also increase the complexity of the production process
[0007] Third, it is expensive
Due to the complex production process and the monopoly of production technology in the hands of foreign companies, the price of this type of lymphocyte separation tube is very expensive at present

Embodiment Construction

[0026] The lymphocyte separation tube of the present invention includes a tube body, and a loose porous material is arranged at the bottom of the tube body. The tube body plus the loose porous material at the bottom of the tube body can be used as the simplest product form of the lymphocyte separation tube of the present invention. When using this kind of separation tube for blood lymphocyte separation operation, the user only needs to add an appropriate amount of lymphocyte separation liquid to the loose porous material first, so that the separation liquid is absorbed by the loose porous material and becomes semi-solid, and then it can be poured into the separation tube. Pour into blood for lymphocyte separation. Lymphocyte separation liquid can also be pre-added into the loose porous material of the tube body to make another product form of the present invention that can directly separate blood lymphocytes.

[0027] The tube body used in the present invention can be prepare...

Abstract

This invention discloses a lymphocyte separation tube, which comprises a tube body. The bottom of the tube body is set loose and porous material. This invention also discloses a method for separating blood lymphocyte by utilizing the lymphocyte separation tube. The lymphocyte separation tube has such advantages as convenient utilization, simple preparation process, and high safety,and no toxicity.

Description

technical field [0001] The invention relates to a cell separation device, in particular to a lymphocyte separation tube. Background technique [0002] Lymphocytes in blood are usually separated by density gradient centrifugation. That is, in a centrifuge tube, first add a certain volume (such as 3 ml) of lymphocyte separation medium, and then carefully spread blood on the interface of the separation medium. Since the density of the separation medium is lower than that of red blood cells and higher than that of lymphocytes, after centrifugation, red blood cells sink to the bottom of the separation medium, while lymphocytes are suspended between the separation medium and plasma. This achieves the purpose of separating lymphocytes in the blood. As shown in Figure 1, from left to right in Figure 1: Add separation liquid to the centrifuge tube; carefully spread the whole blood to be separated; after centrifugation, the red blood cells sink to the bottom of the tube, and the lym...
