Large scale wet electroblotting

[Peter Jenner]

Does anyone know of a manufacturer of a large scale tank electroblotting apparatus 
suitable for electrophoresis gels 20 x 22 cm.   We are planning to use the Investigator
2D electrophoresis system and want to be able to blot up to 5 gels simultaneously.
We would prefer to use a wet blotting system rather than a semi-dry method, to maximize
the recovery of the proteins.

Thanks for any help
