Hi, Does high salt concentration(around 0.7M Nacl) in NiNTA elution do better. And what about the purification of high positively charged protein (like PI 10) in NiNTA. Thanks Debajyoti Dutta On Sat, 28 Jun 2008 Artem Evdokimov wrote : >Ni salt of dodecyl sulphate is not soluble. Therefor

[ccp4bb] Mapmask (Patterson)

2008-06-28 Thread Markus Kroutil
Dear ccp4 users: Where can I find a description of the program Mapmask (Patterson): There are several possibilities to calculate a map ("Patterson", "Patterson from intensity", "difference patterson", "anomalous difference patterson", "Patterson using anom. difference data").. What are the dif
