Hi Maher My version of Overlapmap reports the CC for main chain and for side chain in the log-file (per residue and overall). Have you looked there? -Bjørn On 2011-04-21 14:25, Maher Alayyoubi wrote: Hi Everybody, I posted a question earlier on the bulletin regarding how to calculate the map

Hi Zhen -was concentration higher in old run? Might be monomer-dimer equilibrium, for recent paper, see Benfield et al. (JBC, in press) -we have a miniDAWN with a 'low-high-medium' setting in the back of the setting. Inadvertently changing the setting scales the MW values up and down. Have you run

Dear All, I am having a consistency issue processing my SEC-MALS data. The sample is a 80KD protein which may form a dimer. The experiment I run a year ago shows a major peak at 11.4 ml (GE S200 column), which is calcuated to have a MW of 144kD. There is a minor peak at 10.0 ml. In an effort to
