Electrode Assembly The electrode assembly holds the gel
sandwich. It houses the sealing gasket,
the upper and lower electrodes, and the
connecting banana plugs. The anode
(lower electrode) banana plug is identified
with a red marker and the cathode (upper
electrode) banana plug with a black marker.
Companion Assembly The companion assembly allows you to run
gels 3 and 4. It holds the gel sandwich and
houses the sealing gasket.
Mini Tank and Lid The mini tank and lid combine to fully
enclose the inner chamber during
electrophoresis. The lid cannot be removed
without disrupting the electrical circuit.
The mini tank and lid are also compatible
with other Bio-Rad electrode modules
for blotting, first-dimension of 2-D
electrophoresis, and electroelution.
