Abstract
A technical measure for gel electrophoresis shaping that can make the gel electrophoresis generate no bubbles including in the gel, and can make a gradient gel being more accurate and more stable in quality. When liquid gel enters a collecting trough under continuous driving of a roller in the collecting trough to be injected into a carrier sheet set from a gel output port and a narrow seam, former injected liquid gel can be pushed upwards by latter injected liquid gel, and an accomplished product of gel can be obtained. If the collecting trough is input with two liquid basic materials, the liquid gel continuously output into the carrier sheet set can have a gradient.
Claims6
A method of gel electrophoresis shaping, said method comprising the step of standing a carrier sheet set on a seat;
- said carrier sheet set has a thin sheet receiving space for injecting therein liquid gel, said carrier sheet set is provided on a bottom with an elongated narrow seam;
- said seat is provided with an elongated gel output port with an opening facing upwards, when said liquid gel is injected upwards into said elongated narrow seam and enters said thin sheet receiving space via said bottom continuously from said elongated gel output port, a formerly injected liquid gel with a surface kept horizontal is pushed upwards by latterly injected liquid gel and the latterly injected gel is gradually injected into said thin sheet receiving space and said liquid gel is cured to obtain an accomplished gel product,
- wherein said carrier sheet set includes a front carrier sheet, a rear carrier sheet and two spacing sheets between said front and rear carrier sheets, so that said front and rear carrier sheets form therebetween said thin sheet receiving space;
- a positioning member includes a positioning frame fixed on said seat, two lateral pressing plates pivotally provided at two lateral sides of and in front of said positioning frame;
- a front of said positioning frame is provided with a positioning trough for placing said carrier sheet set;
- a bottom of said positioning trough is provided with an elongated hole in connection between said elongated narrow seam and said elongated gel output port,
- wherein lateral sides of a front wall of said positioning trough is further provided with two upright height adjusting grooves each with a height control plate therein, each of said height adjusting groove is provided thereon with an upper and lower recesses, and said height control plate has a positioning protrusion in cooperation with said upper and said lower recesses;
- said height control plate has thereon two protruding pieces respectively provided on a top and a bottom of said rear carrier sheet;
- and
- A top of a front of said positioning trough is further provided with two pressing cams in contact with an upper edge of said rear carrier sheet.
