Hello dear all.

My non-denaturing PAGE looks a bit non-publisheble because of a smear at sides of lanes, so, my proteins are not like bands, rather like comets with two tails.

Sure, the problem might be easily solved, but I don't know how.

Can you give me some comment on my problem?

Just in case: 5% stacking gel, 12% separating gel, Tris-Glycin running buffer, 40-80 mkg of protein per lane (and I'm afraid I can't use less because it's in-gel enzyme activity experiments, there is not much emzyme in my samples).

Thank you!

Al -

the comet like tails are due to salt. Is dialysis an option at all for you or will the proteins precipitate?

Thanks a lot for the comment.

My protein samples are dissolved in 1xPBS, I don't think there is a lot of salt in it...

Actually, I found some notations on problems like mine.
It might be useful for everybody, so, I'm placing the link here (hopefully, I'm not breaking rules of the forum):

Good luck to all of us, soldiers of desperate fight against the Evil of Darkness. Heh...
