Background
Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) is an important means for separating proteins according to their molecular weights. SDS-PAGE generally uses a discontinuous buffer system, which allows higher resolution than a continuous buffer system. However, the separation gel and the concentrated gel in the discontinuous buffer system need to be arranged in sequence, and the separation gel and the concentrated gel take a long time to solidify after the arrangement. Because the gel can only realize better separation effect if the solidification is sufficient, so the solidification time is inevitable, other works are mainly arranged through the solidification time at present to improve the time utilization rate, the solidification can also be accelerated by raising the temperature, but the separation effect is not good due to the accelerated solidification.
In addition, the gel device is not tightly assembled, so that the gel leakage phenomenon can occur, and the time can be wasted due to the reconfiguration after the gel leakage. Glue leakage is a phenomenon that glue solution flows out through a gap before solidification under the action of gravity, because a common gap is not too large, the glue solution flows out slowly, and in addition, due to the existence of the solidification phenomenon, the glue solution generally only flows out of a small part, but the small part of the glue solution also inevitably leads to rework.
