Easy-to-mount movable equipment capable of storing NKT cells

Abstract

The invention relates to the technical field of biomedical equipment, in particular to easy-to-mount movable equipment capable of storing NKT cells. The equipment comprises a plurality of stainless steel tank bodies of cylindrical structures; a threaded hole is formed in the top of each tank body, a heat preservation layer fixedly adheres to and wraps the outer layer of each tank body, and a protective layer made of elastic rubber fixedly adheres to the outer side of each heat preservation layer; lugs of a square frame structure are symmetrically arranged on the two sides of each tank body, and the lugs and the tank bodies are fixedly welded to form an integrated structure; a round storage cavity is formed in the center of an inner cavity of each tank body, and an annular liquid storage cavity used for storing liquid nitrogen is arranged on the periphery of each storage cavity; a round connecting pipe is fixedly welded to and communicated with the top of each liquid storage cavity; aninternal thread is arranged on the inner wall of the upper portion of each connecting pipe, and the interior of each internal thread is cooperatively provided with a second thread head of a circular threaded rod structure. Cell storage using the equipment is relatively convenient, and the equipment has relatively good practical value and popularization value.

Description

technical field [0001] The invention relates to the technical field of biomedical equipment, in particular to a device for easy installation and removable storage of NKT cells. Background technique [0002] Currently, jars for cell storage are indispensable in biomedical device technology. NKT (natural killer T) cells are a group of special T cell subsets that have both T cell receptor TCR and NK cell receptor on the cell surface. NKT cells can produce large amounts of cytokines. [0003] Its main features are: [0004] 1. Co-express T cell receptor and NK cell receptor. Classical NKT cells are generally CD4+ and DN NKT cells. Among them, NK1.1 is the main surface marker of NKT cells. [0005] 2. Bias usage of TCR gene. Compared with other T cell subsets, NKT cells have a unique restricted expression TCR repertoire. [0006] 3. Accept the lipid antigen presented by CD1d and play a role in innate immunity. [0007] The biological characteristics and immune function of...

Problems solved by technology

However, in the process of specific biomedical experimental research, the inventor usually encounters some situations, that is, it is very troublesome to carry out cell culture every time when NKT cells are used in the experiment process, and it is urgent to use some corresponding storage devices to assist and prolong the cell cycle time. preserve activity
