Yes, CM-Sephadex expands and contracts incredibly. For other than batch methods you will be much better using CM-Sepharose. I guess it is cross-linked sepharose, and doesn't swell up much even in distilled water. What is happening is the negative charges of the carboxy groups repel each other,

[ccp4bb] CM Sephadex C50

Hello All I am using CM Sephadex C50 column for my protein. I equilibrated column with MOPS buffer pH 6.0. But during elution I am using only NaCl2. This looks like changing the bed height. Before starting elution the bed height was around 60cm. After starting elution the bed height decreased

Re: [ccp4bb] about the unique reflections

Presumably it counts all missing reflections in the refinement procedure. Seems wrong! What software are you using? Eleanorr Do an mtzdump to the resolution you used - that gives you a count of observed reflections, plus the possible number of reflections.. On 7 February 2017 at 08:03, Vic Wu
