Problems solved by technology

[0005] Looking at the above methods, it can be found that the current PBMC buffy coat extraction methods have many shortcomings such as long experiment time and difficulty in extracting buffy coat, and the quality of buffy coat is difficult to guarantee. However, if a special sieve plate or a special centrifuge tube is used to simplify the The experimental operation shortens the experimental time and increases the additional experimental cost

Abstract

The invention discloses a PBMC (peripheral blood mononuclear cell) lymphocyte rapid extraction method, which comprises the following steps: extracting a buffy coat from whole blood; adding the buffy coat to a lymphocyte separating solution and conducting centrifuging at a centrifugal rotational speed of 1500-2000rpm, setting centrifugal force speed raising as being 50-80% braked and setting centrifugal force speed reducing as being 50-80% braked; and conducting centrifuging for 15-20min and extracting a buffy coat. The prepared mononuclear lymphocyte product provided by the invention is good in quality and high in extraction efficiency, and the method is simple, short in consumed time, low in amount of consumables and low in cost.

Description

technical field [0001] The invention relates to the technical field of PBMC buffy coat extraction, in particular to a rapid extraction method of PBMC buffy coat. Background technique [0002] The current PBMC experimental method mainly adopts manual operation with timing and constant speed centrifugation, or assists some newly developed special screens and centrifuge tubes for operation. The extraction of mononuclear lymphocytes (commonly known as buffy coat) in the PBMC test method is particularly critical. However, the commonly used experimental methods generally have a long centrifugation time, and the auxiliary special consumables increase additional experimental costs, making the experimental operation of the PBMC test method difficult. Difficult. [0003] Among the current existing methods, the application number CN201510768205.9 "A Method for Separating PBMCs" discloses that the buffy coat is extracted by centrifugation for 20-30 minutes under the conditions of 15-18...
