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

Presumably with placing two conductors at each end of the tray, switching these alternatively on/off would average out the movement of particle through the gel and also perhaps speed the separation in the gel run since the movement is a zig-zag through the matrix.  

try reading some actual journals some time, like Electrophoresis, which has plenty of validated, published research articles on this subject around 1980 +/- 10 years. 

You know, actually RTFM!!

Interesting idea Conner!  I had no idea spark plugs had Pt.  Also, good point Nathan about the point source causing problematic distortion in a 2D gel.  I wonder if a decent electrical field could be created with an evenly spaced array of spark plugs (or small lengths of Pt wire).  Somebody fire up some E field modeling* :)

* COMSOL or ANSYS might be fairly turnkey... or, for the brave, Mathematica/Matlab/NumPy should do it.  I haven't even Googled it (let alone Google Scholar), so forgive me if prior work on the electrode array front is laying in plain sight.

A point electrical source might drag all the DNA to the center of the gel

I had an idea a few days ago about using platinum spark plugs as the electrodes. One could be placed at each end and the center used for the electrical in/outputs. I hope to be building a few boxes soon and would just thread holes for them. Another plus would be that they could be changed out easy if they ever corroded.

Any ideas?
