Dear all,

I have recently had problems with my FPLC gel filtrations using yeast
extracts. In my dispair, I added every single available protease
inhibitor to my extract. Now I have a beautiful result but the protein
comes out with approximately double the size and also runs according to
doubled size on the gel. So, either I have modified my protein or stably
cross-linked it with itself or another protein or ...

The inhibitor I suspect having caused this is iodoacetamide. Can anyone
tell me what the effects of iodoacetamide on proteins are? 

Thank you very much for your help.
