I haven't tried electrophoresis with graphite from mechanical pencils,
but they worked fine for electrolysis of salt water. After a while
they showed some splintering... but FYI, it should probably work for a
single-time use at least.

Otherwise, get some platinum wire... there may be another cheaper
alternative that still corrodes, but at a very very slow rate compared
to whatever... search a bit in the DIYbio archives and you should find
it (I just used the keyword platinum in the archives, and I think the
conversation I'm referring to is called "Non-Platinum Electrophoresis
Electrodes That Don't Degrade").
