Re: [DIYbio] Non-Platinum Electrophoresis Electrodes That Don't Degrade

I have been testing out a bunch of different metals and they either oxidize to death on the minutes timescale or in the case of stainless steel turn the buffer orange/brown.

Platinum wire is pretty expensive ~$1.00 cm^-1. Has anyone had luck with a cheaper metal at 100V or greater with TAE?

I have tried:

Nickel

Stainless Steel 430

Tinned Copper

Thinking of trying Titanium or Nickel Titanium (<= $4 meter^-1). Anyone ever tried these?

Thanks,
