High-flux split type magnetic frame

Technical Field

The utility model relates to a magnetic bead purification device field especially relates to a split type magnetic frame of high flux.

Background

Nowadays, with the development of the biomedical industry, molecular biology experiments are permeating into various aspects of the biomedical industry, such as pathological mechanism research, drug action principle research, clinical diagnosis, and the like. In molecular biological experiments, the purification of target substances is realized by various types of modified magnetic beads. And magnetic beads adsorbing the target substance are enriched by magnetic force provided by the outside, and finally the target substance is purified. The magnetic rack is a commonly used device for adsorbing magnetic beads and is generally composed of a bracket part and a magnetic part. The step that the magnetic frame carries out the enrichment to all kinds of magnetic beads that use in the experiment mainly is for the magnetic bead kind of confirming the use according to the characteristic of target material, how many magnetic beads of calculation needs adsorb the target material, adds the mixing behind the magnetic bead, places the container (like the centrifuging tube) that contains the magnetic bead liquid and stews so that the magnetic bead is fully attracted to the magnetic force side on the magnetic frame, siphons away other liquid that do not contain the magnetic bead, adds other liquid mixing etc.. Because a group of operations of adding liquid → mixing → adsorbing magnetic beads → sucking away liquid without magnetic beads is repeated in the same experiment, the group of operations and the preceding steps are operated in the same container (sample tube), so that the operation time can be greatly shortened, and the possibility of cross influence and error can be greatly reduced.

At present, in molecular experiments, especially in PCR experiments, the magnetic bead purification step is usually performed after a PCR experiment or an enzyme reaction step, and the consumables used by different PCR instruments are different, and the consumables include 0.1ml octa-tubes, 0.2ml octa-tubes, twelve-tubes, 32-well PCR plates, high-order 96-well PCR plates, and low-order 96-well PCR plates, wherein the 96-well PCR plates can be further divided into skirt-free PCR plates, half-skirt PCR plates, and full-skirt PCR plates. In addition to PCR experiments, a pre-protocol for partial magnetic bead purification would use a slightly larger 0.5ml centrifuge tube.

Magnetic racks on the market are various at present, from centrifuge tubes suitable for 15ml and 50ml to deep-well plates suitable for 96-well, and further to PCR plates suitable for 96-well. Magnetic racks suitable for small volume experiments are almost exclusively used for eight-or twelve-channel tubes, or basically only for 96-well PCR plates. The design specially used for the eight-connection tube or the twelve-connection tube is basically that the middle is of a bracket structure, two sides of the bracket structure are respectively provided with 8-hole or 12-hole grooves, a magnetic block or a magnetic strip is arranged at the middle lower side (as shown in figure 1) of the bracket, the middle position of the rear part of the connection tube inserted into the hole grooves is contacted with a magnetic part, and magnetic beads suspended in liquid in the tube can be adsorbed to the area in a short time. Such a magnetic frame has the following problems:

1. the flux is small: one magnetic rack can only operate 2 eight-linkage pipes/twelve-linkage pipes simultaneously, 16 and 24 samples are respectively, if more linkage pipes are needed to be operated simultaneously, a plurality of magnetic racks are needed, the price of a single magnetic rack is about 1000 yuan for domestic goods, more than 3000 yuan for imported goods, if more eight-linkage pipes are used, and the cost is higher when a plurality of magnetic racks are used when the sample flux is relatively large; the difference between the operation time and the magnetic force frame can cause the instability of the experimental result.

2. Almost no compatibility: the magnetic racks are all of integrated structures, so that the universality of the magnetic racks is limited, the magnetic racks are not suitable for 0.5ml centrifuge tubes and 96PCR (polymerase chain reaction) pore plates, and most of the magnetic racks are only suitable for 0.2ml centrifuge tubes and 0.2ml eight-connected tubes/twelve-connected tubes. The incompatibility problem lies in that once a new consumable is needed to carry out a purification experiment, a proper magnetic rack needs to be found, and once the original consumable is completely replaced by the new consumable due to the reasons of flux, cost, quality and the like (for example, the eight-way pipe is replaced by a 96-hole plate due to the flux), the original magnetic rack cannot be used.

The design only suitable for the 96-well PCR plate is that the bottom is a bracket on which magnetic blocks or magnetic strips (as shown in FIG. 2) are regularly distributed, the 96-well plate is placed on or inserted into the groove of the fixed well, and each well of the 96-well plate has a side wall contacting the magnetic part, so that the magnetic beads are concentrated near the area. The existing 96-pore plate magnetic frame mainly has the following problems:

1. the operating requirements for the experimenter are relatively high: the magnetic holder of the 96-well plate with the wells is basically in a closed or semi-closed structure, so that a user cannot see the adsorption condition of the magnetic beads in use, and the adsorption time is too short or the liquid is slightly careless in the operation of sucking the liquid, which can cause the magnetic beads with the target substances to be sucked together with the liquid.

2. Compatibility is generally as follows: the magnetic frame of the 96-pore plate without the pore groove can not fix 0.2ml centrifuge tubes and tube-connecting consumables, and can be fixed only by an external auxiliary tool (a 96-pore PCR tube frame), and the problem is close to that of the magnetic frame with the pore groove after the external auxiliary tool is used; most of the magnetic racks with the holes can be used for holding 0.2ml centrifuge tubes and tube-connecting consumables, but the consumables are closed or semi-closed structures. The adaptation degrees of different pipes and the hole grooves of the magnetic frame are different, and a blind area is formed inside the closed structure support of the magnetic frame, so that consumable materials cannot be adjusted to the position where magnetic beads can be adsorbed through fine adjustment; as the aperture of the magnetic frame is suitable for 0.2ml of pipes, 0.5ml of pipes cannot be adapted to any type of 96-hole PCR plate magnetic frame.

The cost performance of the two magnetic force frames is common, the price of the domestic magnetic force frame is relatively low, but the quality is unstable, and the service life is relatively short; some magnetic racks for domestic small factories to deliver goods sometimes have the situation that the magnetic force of individual holes does not completely reach the standard; the magnetic force of the magnet with excessive quality is stably maintained for at least more than 10 years, and the phenomenon that the magnetic force is obviously reduced occurs when the domestic magnetic frame is used for 3 to 4 years. The imported magnetic rack has the price more than three times that of domestic similar goods. Although the used materials are relatively good, the price is high and the shelf life is long. Even if the non-hole slot magnetic rack with lower compatibility is cheaper than the hole slot magnetic rack, the price of the magnetic rack with over-qualified quality is still more than 3000 yuan, and if the usage amount is larger, certain pressure is caused to the operation of small companies.
