The invention provides a dry electroblotting system for dry blotting gels, in which the system includes an electroblotting transfer stack that comprises an analysis gel and a blotting membrane, an anode, a body of anodic gel matrix juxtaposed with the anode between the anode and the transfer stack, a cathode, and a body of cathodic gel matrix juxtaposed with the cathode between the cathode and the transfer stack, in which the anodic gel matrix and the cathodic gel matrix each comprise an ion source for electrophoretic transfer. The dry electroblotting system does not use any liquid buffers that are added to the system just before electroblotting (such as when the transfer stack is being assembled). The anode, the cathode, or both can be separate from a power supply and provided as part of a disposable electrode assembly that also includes a body of gel matrix that includes ions for electrophoretic transfer.
