Embodiment 1

[0021] A method for extracting and collecting peripheral blood mononuclear cells, comprising the following steps:

[0022] 1) Peripheral blood collection: Collect 100ml of human peripheral blood in a blood collection bag containing sodium citrate anticoagulant. After the collection is completed, the blood collection bag is refrigerated and transported in a sealed sterile transport box at a temperature of 4-8°C;

[0023] 2) Peripheral blood pretreatment: sterilize the blood collection bag containing peripheral blood transported in refrigerated storage in step 1), then transfer the peripheral blood in the blood collection bag to a 50ml centrifuge tube, take samples for counting, and perform corresponding detection;

[0024] 3) Centrifugation: Place the centrifuge tube containing the peripheral blood described in step 2) in a centrifuge, centrifuge at 2500 rpm for 10 minutes at 4°C, adjust the centrifuge to increase speed by 2 and decrease speed by 1, and the blood in the centrifu...

Embodiment 2

[0032] A method for extracting and collecting peripheral blood mononuclear cells, comprising the following steps:

[0033] 1) Peripheral blood collection: Collect 50ml of human peripheral blood in a blood collection bag containing sodium citrate anticoagulant. After the collection is completed, the blood collection bag is refrigerated in a sealed sterile transport box at a temperature of 4-8°C;

Embodiment 3

[0043] A method for extracting and collecting peripheral blood mononuclear cells, comprising the following steps:

[0044] 1) Peripheral blood collection: Collect 80ml of human peripheral blood in a blood collection bag containing sodium citrate anticoagulant. After the collection is completed, the blood collection bag is refrigerated and transported in a sealed sterile transport box, and the refrigerated temperature is 4-8 °C;

[0045] 2) Peripheral blood pretreatment: Sterilize the blood collection bag containing peripheral blood transported by refrigeration in step 1), then transfer the peripheral blood in the blood collection bag to a 50ml centrifuge tube, take samples for counting, and do corresponding detection;

Abstract

The invention discloses a method for extracting and collecting peripheral blood mononuclear cells. The method comprises the following steps: 1) collecting peripheral blood; 2) pretreating peripheral blood; 3) performing centrifuging; 4) extracting plasma; 5) performing plasma inactivation; 6) collecting mononuclear cell layers; 7) centrifuging the mononuclear cell layers; 8) performing cleaning; and 9) extracting mononuclear cells. The invention belongs to the technical field of cell extraction, and particularly provides a method for separating peripheral blood mononuclear cells, which is usedfor obtaining the peripheral blood mononuclear cells by centrifugal extraction of Ficoll lymphocyte separation liquid and is high in cell yield and high in activity.

Description

technical field [0001] The invention belongs to the technical field of cell extraction, and specifically refers to a method for extracting and collecting peripheral blood mononuclear cells. Background technique [0002] Peripheral blood mononuclear cells are cells with a single nucleus in peripheral blood, mainly including monocytes, lymphocytes (B cells and T cells), phagocytes, dendritic cells and NK cells, etc. These cells are the body's immune response important cells. Peripheral blood mononuclear cells are rich in peripheral blood stem cells, which can treat metabolic genetic diseases, tumor diseases, immunodeficiency diseases, malignant blood diseases, etc. [0003] In recent years, immunotherapy, as the fourth mode of comprehensive tumor treatment, has been more and more widely used. Studies have found that peripheral blood mononuclear cells can proliferate and differentiate in vitro for the treatment of diseases. In addition, peripheral blood mononuclear cells are...
