  • Patent number: 10203304
    Abstract: A precast gel and blotting membrane combination unit and method of use. The device includes two plates, each plate having a conductive opaque region with conductive polymers and a transparent region having static-dissipative polymers. Between the plates are a gel matrix and blotting membrane. The device is placed in a tank capable of both performing the electrophoresis phase and transfer phase of a western blot. During the electrophoresis phase, current flows from a pair of electrophoresis electrodes to separate proteins by size. The user can visualize the extent of protein separation by observing a tracking dye through the transparent region. After the electrophoresis phase, voltage is switched to a pair of transfer phase electrodes. The device allows current to flow through the conductive opaque regions of the plates to transfer separated proteins to a blotting membrane directly after electrophoresis without having to remove or reorient the device in the tank.

  • Patent number: 9983168
    Abstract: A precast gel and membrane combination unit for use in gel electrophoresis and membrane transfer for protein analysis, and method of use. Transparent electrically conductive polymer plate(s) house an electrophoresis gel and immunoblotting membrane. The gel and membrane are positioned between two plates of conductive polymers or plates having an electrically conductive layer or film. During the electrophoresis step, electric current moves proteins through the gel allowing for protein separation. Then, without removing or reorienting the gel or apparatus, the electrical contacts are switched to allow the flow of electricity to run perpendicularly through the gel via the conductive polymers, which will allow the proteins to transfer to the membrane housed in the same precast gel and membrane combination unit. The apparatus allows the user to visualize the steps of protein separation and protein transfer without transferring the gel between electrophoresis and transfer steps.
