[ccp4bb] Jan 31 deadline for applications: Postdoctoral Fellow Positions - The Hospital for Sick Children Research Institute (Toronto, Canada)

2020-01-22 Thread Jean-Philippe Julien
Job description Dr. Julien’s laboratory at The Hospital for Sick Children Research Institute (Toronto, Canada) is looking for two Postdoctoral Fellows to join our Structural Biology team. By using a combination of biochemical, biophysical, immunological and structural techniques, the successful

Re: [ccp4bb] Unusual monomer-monomer interface in crystal

When the JCSG was in production, we would routinely collect X-ray emission spectra from our samples to look for metals. We also saved all crystals after data collection and if we saw extra anomalous peaks in the maps during refinement, we would put the crystal up again and collect quick low

Many thanks for all of the suggestions. Ni2+ or Zn2+ seem to be the most likely culprits, but I plan to carry out a fluorescence scan at my next beam session. While it’s interesting that others have observed crystallization-driven formation of disulfides, the binding of a metal ion at the given

This conversation brings up the question of whether it would be good practice to always do a fluorescence scan of a crystal sample, whether it is known to be a metalloprotein or not... Energy dispersive X-ray fluorescence spectra (accessible at most synchrotron sources at this point) can often

Hi Chris, it could be all Ni besides Zn. I've seen Ni carried over from the initial metal affinity chromatography I presume. Cheers Christian Chris Fage schrieb am Di., 21. Jan. 2020, 21:23: > Thanks to Guenter and Eleanor for their replies. I mentioned that there is > not adequate space for

The BCA Spring Meeting is fast approaching and the BSG committee are still looking for nominations for the Early Career Prize. Anyone who has recently obtained a personal fellowship, a lectureship or equivalent in the field of Structural Biology will be considered, though preferably with an

Re: [ccp4bb] coiled coil molecular replacement

Hi all, Just to conclude on this - ARCIMBOLDO via CCP4 in coiled coil mode worked quite nicely in the end now that I finally had time to work through it - took a few days with 8 x 20 aa peptides as the search set on my old iMac but the end result was fine :). So didn't have to try other options

Hello, You could run Image Quant TL in a VM (parallels, vmware or virtual box). https://bmi.cchmc.org/resources/software/imagequant-tl For this appliation (arrays), we use an old program called VisualGrid that is no longer available and run it an isolated XP VM via virtual box (in linux).
