[ccp4bb] offtopic: related to protein purification

2014-08-03 Thread Sonia Majumdar
Dear all, I am working on a GTPase with two tandem G-domains. While doing ITC experiments the heat change obtained is very poor 0.1ucal/sec, however the ITC profile is showing gradual saturation. The n value is very poor 0.33. I presumed the protein has bound GDP and tried to separate the nucleoti
