Many thanks AK. I s'pose 'enrich' would be a better word? The hope is to 
do a bit of proteomic work and subunit relative abundance analysis on 
it. Enough to run relative pure stuff on a gel would be handy. I had a 
little play with the Protein G-sepharsoe I found but ended up with 
bucket loads of what I assume is Protein G on my gels. I also think it's 
a little too old for successful IP, so I'm getting a new batch!
