Dear Marcus,

We have been using the Biorad Protean II for second dimension with 16 x 20
cm plates (18 cm IPG strips fit nicely including mol. wt. markers)....4
gels per tank and have two tanks connected in series to the recirculating
cooler unit. Approximately 2.5 litres of running buffer per tank. We can run
this twice a day to give us 16 gel throughput in a 24 hour period. The
multi-casting chamber permits 12 gels to be poured simultaneously. Uniform
heat transfer is an issue so we really crank up the flow on the cooler.
Actually pouring and running the gels is not the bottleneck the
staining/destaining is. Especially when using a silver staining protocol
there are so many steps, it really takes a lot of time.

        Dear colleagues,

        we are doing 2D-PAGE on a Multiphor II/ Hoefer SE600 (using double
gels)
        system. Since we are currently setting up a proteome project for
        Dictyostelium, I am now thinking about purchasing a high throuput 2D
system
        for these studies. I am especially interested in the second
dimension and
        have already thought about the Hoefer IsoDalt, BioRad's MultiProtean
XL and
        Genomic Solutions Investigator system. The system should be capable
of
        using 18 cm IPG strips and running 10 or 12 second dimension gels in
        parallel.
        What do you think about the three systems? Are there any more
systems which
        accomplish the mentioned conditions? What are their major pro's and
con's?
        The IsoDalt systems needs large amounts of running buffer, how does
this
        compare to the other two? As far as I could figure out, the cost are
        approximately the same for all three systems so this should play a
minor
        role in the decision. Any information will be highly appreciated.

        Yours sincerely,
        Marcus Macht
