We do not recommend using gels past their expiration date because over time, the polyacrylamide hydrolyzes to acrylic acid and ammonia and this will affect the resolution of the proteins. Breakdown of polyacrylamide matrix is identified by:
- Ghost bands and doublets, seen first in the high molecular weight proteins
- Smiling of dye front across the gel, with bands in outer lanes becoming very slanted - proteins run slower there due to change in pH and pore size over time.

This is not really recommended, but it is always possible to increase run time by lowering the voltage of the run. In general, the relationships are linear - i.e., decreasing voltage by half will double the run time.

If you are running the gel at constant voltage, you do not need to increase the voltage regardless of the thickness of the gel.

Using constant voltage allows the current and power to decrease during the run, providing a safety margin in case of a break in the system. Having lower power is a safety benefit and will also decrease the chances of experiencing an overheating of the gel. Further, the constant voltage setting does not need adjustment to account for differences in number or thickness of gels being run.
