Re: [DIYbio] Capillary electrophoresis that I made but can be improved

I was trying something along the paper attached bellow but it was very finicky since I didn't have correct buffer and my pvp is lower MW. It should work as they showed in that paper but I need more time to nail it down (also order correct buffers). Since I am going away for next 2 months, I just wanted to share what I had till now just in case someone else wants to do their own stuff. The whole capacitive sensing is very powerful, and simple enough in my opinion so I just wanted to share.

Nice! So it seems you never tried it with DNA? From what I can
remember, mass-to-charge is constant regardless of DNA length, thus
you need activated capillary walls to aid effect separation.
(easiest to read reference on internal coatings for DNA
sequencing/separations I could quickly find is pg 130 here:
