Hi, Try modeling a zinc close to the histidine and then do one round of refinement the density will improve close to that area, generally a zinc ion coordinated to histidine also has a water molecule close to the zinc. HTH, Shya On Tue, Jun 19, 2012 at 5:47 AM, Lianying Jiao wrote: > Dear all, >

Hi, Did you try using a different column like Superose 6? This column works well to separate large molecular weight proteins including oligomers. Ideally if your solution is not cloudy (coming out of void volume) those are not aggregates those might be oligomers. HTH, Shya On Tue, Feb 21, 2012 at
