migration of a non denaturant PAGE

[Stefi~]

I have two proteins with very similar mol weight (and very similar (but not
identical!) pI. When I do a SDS-PAGE and blotting I find bands at the same
position. As my antibodies are not very specific, I'd like to use blotting
on a non denaturant PAGE, hoping I'll have different migration. What do u
think?
