Embodiment 1

[0029] see Figure 1 to Figure 5 As shown, Embodiment 1 of the present invention provides a protein dialysis device, including a driving device and a dialysis turret; the driving device is used to drive the dialysis turret to rotate; the dialysis turret is used to carry a dialysis bag, wherein the dialysis turret includes a wheel shaft 102 and the wheel fan; the wheel fan is installed on the wheel shaft 102 through the wheel spokes 103, and the wheel spokes 103 are arranged along the radial direction of the wheel shaft 102, and the driving device drives the wheel shaft 102 to rotate.

[0030] In the protein dialysis device provided in this embodiment, the dialysis bag is installed on the dialysis turret, and the dialysis turret is driven to rotate by the driving device, so that the dialysis bag can also be rotated, so that the dialysis buffer can also be moved; The protein dialysis device provided in this example abandons the method of stirring the dialysis buffer with a magne...

Embodiment 2

[0049] The protein dialysis device in this example is an improvement on the basis of Example 1. The technical content disclosed in Example 1 will not be described repeatedly, and the content disclosed in Example 1 also belongs to the content disclosed in Example 2.

[0050] In this embodiment, the protein dialysis device further includes a drain pump and an inlet pump. The drain pump is used to discharge the dialysis buffer in the container (such as a beaker); the inlet pump is used to draw the dialysis buffer into the container. This facilitates draining the old dialysis buffer in the container and injecting new dialysis buffer.

Embodiment 3

[0052] A protein dialysis system provided in Embodiment 3 of the present invention includes the protein dialysis device provided in Embodiment 1 or Embodiment 2.

Abstract

The invention relates to the technical field of bioexperiment devices, in particular to a protein dialysis device and system. The protein dialysis device comprises a driving device and a dialysis rotating frame, the driving device is used for driving the dialysis rotating frame to rotate, the dialysis rotating frame is used for carrying a dialysis bag and comprises a wheel shaft and wheel leaves,the wheel leaves are mounted on the wheel shaft through wheel spokes which are arranged along the radial direction of the wheel shaft, and the driving device drives the wheel shaft to rotate. The protein dialysis system comprises the protein dialysis device. Sample leakage, mutual winding of multiple dialysis bags and damage to the dialysis bags when a magnetic stirrer is used can be avoided, andexudation of micromolecular protein or other impurities in the dialysis bag can be accelerated to achieve the objective of protein purification.

Description

technical field [0001] The invention relates to the technical field of biological experiment devices, in particular to a protein dialysis device and system. Background technique [0002] At present, protein dialysis mostly puts the dialysis bag into the dialysis buffer, and then uses a magnetic stirrer to drive the magnetic rotor to rotate, so that the dialysis buffer forms a vortex, thereby promoting the permeation of small molecular proteins or other impurities in the dialysis bag. Retain the target macromolecular protein to achieve the purpose of protein purification. Some problems often occur during the use of a magnetic stirrer, such as: the dialysis bag sealed with a clip or tied with a rope, the magnetic rotor may collide with the sealing clip and cause the mouth to loosen, causing the sample to leak out; when multiple samples are dialyzed, it may The intertwining between the dialysis bags will affect the dialysis effect; if the speed of the magnetic rotor is not adj...
