Hi Alan, I think new AKTA collector can be refrigerated. If this is not an option, consider putting only collector in the cold cabinet and cooling down the buffers. Also, you can put only columns and fraction collector inside cabinet which has side port for such use. Although you will have to us

Dear Matthew, You seem to have been unlucky with this data collection. STARANISO would be prepared to see significant data extending to 2.0A along a*, 2.7A along b*, and 1.7A along c*. The latter limit, however, involves some guess work via the fitting by an ellipsoid of a cut-off surface tha

hi alan, why do you want to put the thing in a cold cabinet? if you have protease problems, there are better ways to get rid of them than exploiting Q10. on the other hand, you'll increase viscosity and thus slow down the flow rates. also, the high humidity will reduce the lifetime of your Äkta

*Please* dont throw good 1.8A data for the sake of statistics! You should see more detail along certain directions You will publish your structure providing honest details of the anisotropy (I hope..) but it is the map quality that matters .. Eleanor On Sun, 21 Jun 2020 at 15:16, Matthew Snee < ma

Dear All Many thanks to Johann for the suggestion of Topsearch - rather pleasingly our tetramer is novel in the tetrameric arrangement, but each of the dimers has its DNA recognition helices in agreement with several hits 😊a win all round Bringing joy to my lockdown. Best Andy ###

Hi everyone. I have an x ray structure that I am finishing up, and there are a few ambiguous regions where the peptide is poorly resolved. The data is highly anisotrophic, and requires truncation to around 2.4A to achieve acceptable merging stats, although there is data in the "good" direction

Thanks to all of you pointing me towards ProtCID, but unless I'm mistaken this works only for deposited co-ordinates / PDB entries? I was more looking for something that would take my (yet to be deposited) PDB file, with its inherent tetrametric hth fold, and find similar folds in similar arra

Thanks Boaz for the SSM heads up. I was much too DALI-centric! One last point, if anyone can offer an opinion - I presume most methods will match but only within ASU contents. Does any approach utilize deposited "biological unit" classification or (better still) crystallographic symmetry oper
