Definitions

  • the first and second electrodes and first and second conductors may be made from a nickel foil having an adhesive on one side so that the electrodes and the conductors may be securely attached to the buffer tank and the lid.
  • the electrodes corrode and become unusable after several runs, either the electrodes or the entire apparatus may be replaced.
  • the substantially vertical and substantially horizontal electrophoresis apparatus could also be loaded and run in an automated system.
  • the registration key is used by the automated system to locate the wells in the gel relative to the apparatus.
  • An automated loader having micropipette tips automatically loads the samples to be tested into the wells.
  • a device can be used to puncture holes in the lid through which the samples may be loaded.
  • the lid is removed before loading the samples in the wells.
  • the automated system then applies the necessary electricity to run the electrophoresis process.
  • the automated system may also photograph the results ofthe testing for subsequent study and analysis.
  • first conductor 204 and second conductor 208 are shown on the first side of lip 112.
  • First electrode 404 is shown adjacent first conductor 204 on lip 1 12.
  • First electrode 404 extends downwardly into an electrophoretic area 420 created inside buffer tank 104.
  • second electrode 408 is shown adjacent second conductor 208 on lip 112.
  • Second electrode 408 extends downwardly into electrophoretic area 420. Electrodes 404 and 408 extend downwardly all the way to the bottom of buffer tank 104 so that when buffer solution is poured into buffer tank 104, a portion of electrodes 404 and 408 come into contact with the buffer solution.
  • the electrodes can be made from Nickel tape. Altematively, the electrodes could be made from stainless steel tape. As discussed above with respect to the conductors, other metal foil materials can be used to make the electrodes, as would be apparent to one of skilled in the relevant art. Similarly, as discussed above, metal materials can be deposited onto the buffer tank to form the electrodes ofthe present invention.
  • FIG. 5 is a simplified perspective view of buffer tank 104 showing electrophoretic area 420.
  • first electrode 404 is an L-shaped piece of material. A small portion of first conductor 204 is also visible on lip 112.
  • second electrode 408 is not visible from this perspective view, in the preferred embodiment, the shape of second electrode 408 matches that shown of first electrode 404.
  • Second electrode 1304 extends downwardly from the bottom of lid 1208 so that when lid 1208 is placed on top of buffer tank 1204, second electrode 1304 contacts the buffer solution in tray 1250 to complete the connection.

Abstract

L'invention porte sur un appareil à électrophorèse (100). Un premier mode de réalisation de la présente invention est utilisé pour séparer des protéines ou des acides nucléiques par électrophorèse. Ce mode de réalisation comprend un réservoir tampon (104) qui contient une zone d'électrophorèse. Une première électrode est montée sur une première partie de l'appareil et une seconde électrode est montée sur une seconde partie de l'appareil. Un premier conducteur et un second conducteur sont placés sur le réservoir tampon (104) et fournissent des voies conductrices partant d'une source d'énergie (120) pour aller, respectivement, à la première électrode et à la seconde électrode. Un gel est introduit dans le réservoir tampon (104) et deux coussinets de mousse à alvéoles ouvertes, saturés dans une solution tampon, sont placés dans le réservoir tampon (104). Un couvercle (136) vient fermer le dessus du réservoir tampon.
