Description

Prefabricated rubber plate

Technical Field

The utility model belongs to the technical field of electrophoresis devices, and particularly relates to a prefabricated rubber plate.

Background

Electrophoresis cells are commonly used in biochemical experiments to separate protein molecules of different sizes in a mixture by polyacrylamide gel steric hindrance.

In use, a gel plate containing polyacrylamide gel is fixed on an electrode frame of a vertical electrophoresis tank to form a closed inner cavity. Then filling the electrophoresis buffer solution into the gel of the closed inner cavity of the electrode frame and the gel which is not covered by the upper edge of the rubber plate, and simultaneously adding the specific electrophoresis buffer solution into the gel which is arranged above the anode platinum electrode and is not covered by the lower edge of the rubber plate in the outer tank to form a current loop between the anode electrode of the outer tank, the polyacrylamide gel, the cathode platinum electrode of the inner cavity of the electrode frame and the direct current power supply. After the mixed protein sample was added, the dc power was turned on. Proteins of different molecular sizes as anions move to the anode in the polyacrylamide gel, and finally separation is achieved.

At present, various products of vertical electrophoresis tanks on the market have many structures for fixing and maintaining the seal between the gel sheet and the electrode holder, such as bolts, eccentric handles, wedge-shaped plates, and the like. And keep sealed structure all need carry out the U-shaped to the frame of offset plate and press to guarantee the closure of inner chamber, in case the condition of weeping will lead to the failure of experiment, consequently in the actual operation process, often need exert great clamping-force to the offset plate.

At present, various offset plate cores on the market are including inner panel and the planking that have the length difference, and the both sides edge of inner panel and planking is through the certain thickness sealing strip of centre gripping to form the encapsulating space between inner panel and planking, for the effect that promotes the experiment, need keep the stability in encapsulating space when the experiment, make polyacrylamide gel keep at accurate cuboid structure, make the electric current when the electric current flows through the polyacrylamide gel keep relatively stable, guarantee the race of protein molecule and glue the effect. And the great clamping-force of electrode holder often can extrude the offset plate, causes the deformation of offset plate, and especially the lower limb of offset plate is owing to lack the support of sealing strip, when sealed fixed, very easily produces deformation to influence the effect of experiment.

Chinese patent CN202021391856.3 is an electrophoresis rubber plate, which comprises a bottom plate, a cover plate and a rubber plate comb, wherein the bottom plate is provided with a positioning clamping groove, a conductive groove and a first rib, the cover plate is provided with a second rib, wherein the first rib is U-shaped for reinforcing the strength of the bottom of the rubber plate, which plays a role of supporting and fixing the bottom of the rubber plate, and the conductive groove is arranged above the bottom of the first rib; the cover plate is matched with the first convex edge of the bottom plate through the second convex edge to form a gel bin in a surrounding mode, and the circuit is conducted through the conducting groove.

In addition, a glass rubber plate is adopted in the prior art, and although the glass rubber plate is not easy to deform, during an experiment, the experiment personnel needs to manually pour glue, so that the operation is inconvenient; and the glass cement plate also has the defects of low strength, frangibility and the like.

In addition, in the prior art, in order to enhance the strength of the rubber plate, the strength of the rubber plate is enhanced by thickening the thickness of the prefabricated rubber plate and adopting high-strength rubber plate materials and other modes, but the prefabricated rubber plate belongs to consumables and needs to be discarded after being used once, so that the manufacturing cost of stirring is greatly increased by adopting the high-strength rubber plate materials or thickening the prefabricated rubber plate and other modes; and the mode of thickening prefabricated offset plate often leads to, and the condition of not adaptation takes place when offset plate and current electrode frame reciprocal anchorage, and the range of application is less.

Therefore, a high-strength and non-deformable rubber plate structure is further required to solve the problem.
