I have problems with my SDS-PAGE: The bands grow wider the further they
have run and the resolution grows bad: bands at the the top seem to be
ok, while those at the bottom are blurred and much bigger than the ones
My samples are bacterial membrane proteins or whole cell extracts in
sodiumphosphate buffer.

Thanks in advance for any help!
