Concentrating proteins already in SDS sample buffer?

Hi all.

Exactly what the subject says.  I'm looking for a way of concentrating a 
protein sample that I have already treated with SDS_sample buffer.  The 
sample is pretty high in salts already so I don't want to simply freeze 
dry it.  Does anyone have any sort of precipitant method that could be 
used - would cold MeOH work.  I want to concentrate the sample so that I 
can get enough of a fairly minor band onto pvdf for N-terminal sequencing.
