proteomics, a question about the running buffer in the SDS step

Dear colleagues,

On the paper published in ABRFNews, March 98 by Walsh et al, "Setting Up Two
Dimensional Gel Electrophoresis for Proteome Projects", there is an anode
electrode buffer ( only 0.75 M Tris pH 8.8 and 0.005% sodium azide: no
glycine, no SDS) and a cathode electrode buffer (192 M Glycine, 0.1% SDS, pH
8.3 adjusted with Tris). The anode buffer can be re-used during 20 gel runs.
Considering the large volumes of buffer used in the second dimension anode
tanks, this proposal makes a great economy. I would greatly appreciate your
experience using this running buffer (any influence on the quality of the
separation) that I found highly attractive.

Thanks in advance for your time and advice,
Lila Castellanos-Serra
