Description

Technical Field

[0001] The present invention relates to the field of biomacromolecule separation technology, and in particular to an electromagnetic composite biomacromolecule separation technology and equipment. Background Art

[0002] Electrophoresis tanks are often used in biomedical biomacromolecule separation experiments. The principle is that the terminals of the electrophoresis tank include positive and negative electrodes, and the positive and negative electrodes are connected to the positive and negative output terminals of the DC power supply respectively. The anode electrode inside the electrophoresis tank, various gels with a spatial grid steric structure, the cathode electrode in the electrophoresis tank, the conductive buffer solution between the cathode end of the immersed gel and the cathode electrode of the electrophoresis tank, and the anode end of the immersed gel and the anode electrode of the electrophoresis tank form a DC circuit loop.

[0003] The mixture of biological macromolecules (DNA or RNA or protein) of different molecular weights in the negative ion state after treatment is powered by the DC electric field of the electrophoresis tank, and migrates from the cathode end to the anode end of the electrophoresis tank in the gel with molecular sieve effect. The larger the molecule, the greater the migration resistance in the gel. Under the same electrophoresis starting point and electrophoresis time, the separation of mixed biological macromolecules is achieved. Common electrophoresis tanks on the market include horizontal electrophoresis devices, vertical electrophoresis devices and tubular electrophoresis devices.

[0004] There are many drawbacks in the existing electrophoresis methods and equipment. The positive and negative electrodes in the electrophoresis tank 1 of the existing various electrophoresis methods and equipment are only fixedly distributed at the two ends of the gel 3, and the positive and negative electrodes at the output end of the DC power supply are also fixed. In this way, at the far ends of both sides of the entire gel, the electric field movement direction 4 of the biomacromolecules 2 is in an eight-shaped direction, and the direction has a certain tilt angle, such as Figure 1 The outward-facing movement direction will lead to incomplete separation and may cause leakage and other unexpected situations.

[0005] With the study of biomagnetism, it is found that biological macromolecules themselves also have certain magnetic material properties, which are manifested as biological paramagnetism under certain conditions.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Example 1

[0030] An electromagnetic composite biomacromolecule separation technology, the simplest technology is to directly add a strong electromagnetic field in the electrophoresis tank of the existing electrophoresis equipment, using a large magnetic field generating component, such as Figure 2 , 3 As shown, the magnetic field generating assembly includes an induction coil 14 and a magnetic field conductor 13 disposed in the induction coil 14. The induction coil includes a metal coil and a current regulator 12 and a switch 15 connected in series with the metal coil. The switch 15 and the current regulator 12 are respectively connected to two poles of an external DC power supply.

[0031] The gel 3 in the electrophoresis tank and the electric field generating device are both existing technologies and will not be described in detail in this embodiment.

[0032] The electric field generated by direct current is a special substance that exists in the space around the electric charge and the changing magnetic field. This substance is different from ordinary physical objects. Although it is not composed of molecular atoms, it is an objectively existing special substance. The magnetic field is a special substance that cannot be seen or touched. The magnetic field is not composed of atoms or molecules, but it exists objectively. The magnetic field has the radiation characteristics of waves and particles. Within a certain period of time, electricity can generate magnetism, and magnetism can also bring electricity. The changing electric field and the changing magnetic field constitute an inseparable unified field, which is the electromagnetic field, and the propagation of the changing electromagnetic field in space forms electromagnetic waves. In the present invention, the magnetic field can affect the electric field, ensure that the electromagnetic field is evenly distributed in the segmented area of ​​the gel, ensure the linear motion of the biomacromolecules, and will not appear outward.

[0033] When in use, the electric field movement direction 4 of the biomacromolecule 2 is along the electric field direction, and synchronously, the magnetic field movement direction 5 of the biomacromolecule 2 also works synchronously, and the electric field direction and the magnetic field direction are the same. The two work together to achieve linear movement of the biomacromolecule along one direction without deviation, thereby ensuring the separation effect and improving the separation accuracy of large molecular weight biomacromolecules.

[0034] This embodiment describes the preliminary use of the combined action of electric and magnetic fields, which is forward-looking but not universal.

[0035] The present invention adds a magnetic field generator in the electrophoresis tank. The electric field generator generates an electric field. Biomacromolecules are essentially charged biomolecules, which migrate under the action of the electric field. The biomacromolecules themselves also have certain magnetism. The magnetic field generated by the magnetic field generator will also cause the biomacromolecules to migrate under the action of the magnetic field. The two cooperate with each other to ensure that the biomacromolecules maintain linear motion during separation and will not have directional deviation.

[0036] The invention has reasonable design and good practical use effect, and has created a precedent for using magnetic field in separation of biological macromolecules.

[0037] Example 2

[0038] like Figure 2 , Figure 4 As shown, an electromagnetic composite biomacromolecule separation technology has been greatly improved in the existing equipment, which is more practical and has better effect. The specific improvement is: the gel in the electrophoresis tank 1 is divided into several segmented areas in parallel along the material separation direction, and each segmented area has an independent electric field and magnetic field. The electric field and magnetic field in all segmented areas are controllable; the electric field and magnetic field work together to drive the biomacromolecules to move, and ensure that the movement direction of the biomacromolecules in all segmented areas is parallel.

[0039] The electric field is each segmented electric field outputted by the same DC power supply through a plurality of terminal assemblies, and the terminal assemblies correspond one to one with the segmented areas. The magnetic field is a combined magnetic field, including a plurality of magnetic field generating assemblies corresponding one to one with the segmented areas; the magnetic field generating assemblies and the terminal assemblies are electrically connected to the same DC power supply. The magnetic field generating assembly includes an induction coil 14 and a magnetic field conductor 13 arranged in the induction coil 14. The induction coil 14 includes a metal coil and a current regulator 12 and a switch 15 connected in series with the metal coil, and the switch 15 and the current regulator 12 are respectively connected to the two poles of the DC power supply. In this embodiment, all the induction coils are the same, and the number of turns and winding direction are the same.

[0040] The gel 3 in the electrophoresis tank and the electric field generating device are both existing technologies, and will not be described in detail in this embodiment. In this embodiment, the gel part is used in sections, which ensures a more precise separation.

[0041] When in use, the electric field movement direction 4 of the biomacromolecule 2 is along the electric field direction, and synchronously, the magnetic field movement direction 5 of the biomacromolecule 2 also works synchronously, and the electric field direction and the magnetic field direction are the same. Under the cooperation of the two, the movement directions of the biomacromolecules in all segmented areas are parallel, and there will be no deviation in the movement direction, thereby ensuring the separation effect and improving the separation accuracy of large molecular weight biomacromolecules.

[0042] The present invention adds a magnetic field generator in the electrophoresis tank. The electric field generator generates an electric field. Biomacromolecules are essentially charged biomolecules, which migrate under the action of the electric field. The biomacromolecules themselves also have certain magnetism. The magnetic field generated by the magnetic field generator will also cause the biomacromolecules to migrate under the action of the magnetic field. The two cooperate with each other to ensure that the biomacromolecules maintain linear motion during separation and will not have directional deviation.

[0043] The invention has reasonable design and good practical use effect, and has created a precedent for using magnetic field in separation of biological macromolecules.

[0044] Example 3

[0045] This embodiment is based on the embodiment 2, and the magnetic field generating components are optimized as needed.

[0046] When other technologies remain unchanged, the magnetic field generating component includes one induction coil or two induction coils.

[0047] When the magnetic force of the magnetic field is small, there is one induction coil, which is installed on the electrophoresis tank corresponding to one end of the segmented area.

[0048] When a large magnetic force is required, two induction coils are provided, and the two induction coils are installed on the electrophoresis tanks corresponding to the two ends of the segmented area, and the magnetic field directions are consistent. All the induction coils are the same, and the number of turns and winding directions are the same.

[0049] When in use, the electric field movement direction 4 of the biomacromolecule 2 is along the electric field direction, and synchronously, the magnetic field movement direction 5 of the biomacromolecule 2 also works synchronously, and the electric field direction and the magnetic field direction are the same. Under the cooperation of the two, the movement directions of the biomacromolecules in all segmented areas are parallel, and there will be no deviation in the movement direction, thereby ensuring the separation effect and improving the separation accuracy of large molecular weight biomacromolecules.

[0050] This embodiment adds a magnetic field generator at one or both ends of the electrophoresis tank, and utilizes the characteristics of the magnetic field on the movement of biomacromolecules to achieve linear motion during the separation of biomacromolecules without directional deviation. It has a reasonable design, a simple structure, and good practical effect, creating a precedent for the use of magnetic fields in the separation of biomacromolecules.
