2 Mini-Trans-Blot Electrophoretic Transfer Cell
This short 4 cm electrode distance allows generation of
higher driving forces to produce efficient protein transfers.
A second feature of the electrode module is that it is
offset to accommodate a blue cooling unit. The cooling
unit, which is completely contained within the Mini
Trans-Blot cell, absorbs the Joule heat generated during
rapid electrophoretic transfers. The advantages of having
an internal cooling unit include elimination of an expensive
external cooling bath and avoidance of cumbersome
cooling tubing. Other features of the Mini Trans-Blot cell
include gel holder cassette latches for easy handling, color
coordinated cassettes and electrodes to insure proper
orientation of the gel during transfer, and an efficient
design which simplifies insertion and removal of the
cassettes from the electrode assembly. These features
result in an electrophoretic transfer system which is easy
to use and produces excellent blotting results.
