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

I can't really find much on chrome plated wire online or a place that sells it. Any ideas?


Graphite rods look like an ok solution but seem complicated to attach and use without breakdown of other metals.

I think the Pearl Gel Box used chrome-plated stainless steel? Graphite is another popular option.

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,
