Abstract
The utility model discloses a device for separating mononuclear cells from whole blood, comprising a centrifuge tube and an upper cover, wherein the top of the centrifuge tube is open, and the bottom of the centrifuge tube is closed; the upper cover is closely connected to the top of the centrifuge tube; and a semipermeable membrane is arranged inside the centrifuge tube and used for dividing the inside part of the centrifuge tube into two parts. The device disclosed by the utility model can be used for directly obtaining high-purity peripheral blood mononuclear cells (PNMC) by directly pouring peripheral blood into the centrifuge tube for centrifugation, thus the operation time is saved greatly and the quantity of the obtained PBMC is high.
Description
Technical field
The utility model relates to cell culture technology field, relates in particular to a kind of device of separation of whole blood mononuclearcell.
Background technology
Whole blood refers to peripheral blood or Cord blood, mononuclearcell in whole blood is as generating in vitro many cellulous raw materials, in fundamental research and cell therapy field, have demand widely, the method for the mononuclearcell in extraction whole blood at present used is traditional Ficoll method.
Contriver research process in find, there is following defect in the method: length consuming time, whole step need to reach 1.5 hours; Operating process is loaded down with trivial details, and it is especially careful in the time adding sample and extract tunica albuginea layer, to need; Target cell purity is not high.
