Help with EMSA minigel conditions

I'm trying to convert my electrophoretic mobility shift assay (EMSA)
from a large gel format (20 cm X 20 cm) to a minigel format (BioRad
Mini-Protean II). For the large gel format the running conditions were
constant 35 mA at 4 deg C for 4 hours. I believe constant 35 mA for a
minigel would be too much power for the protein-DNA interactions to be
maintained and would finish the run very quickly. Can anyone suggest
the proper running conditions for my application? BTW, I'm using a high
ionic strength buffer (Tris/glycine/EDTA).
Any help would be greatly appreciated. Thanks in advance.
