Dear Sir, I have a query regarding the Biacore 1k+ - NTA chip experiment. I have performed an interaction study between a his-tagged protein and peptide. I am facing some problems in the experiment, and I am guessing it is with the EDTA regeneration. The response of the 0 µM concentration (1X PBS

Dear Kay, do you use devtoolset (Red Hat Developer Toolset)? It's a set of relatively new tools and compilers, up to GCC 12, for RHEL7. It might be the best solution unless you need GCC 13+. Marcin On Wed, Mar 26, 2025 at 6:18 PM Kay Diederichs wrote: > > Dear all, > > when compiling XDS or any

Timothy Snyder says it thus in Rule One from On Tyranny: Do not obey in advance! Too many, unfortunately will decide to obey in advance, when a unified resistance would serve us all better in the long run. We need more to chose the path cleared by Glorian Borgstahl. Charlie On Mar 12, 2025,

[ccp4bb] PyVOL and new versions of PyMOL

Hi all, Just a quick notice if you are PyVOL users. I have accidentally updated my PyMOL to version 2.6.1 (I find version 3.1 horrible) and found out that the latest PyVOL 1.7.8 installs correctly but doesn’t work due to some deprecated arguments in the code. If you want to keep using it, do not

There is a way to do this in pymol. Change the mouse mode to editing mode and click the two ends of the loop, then you should be able to drag it around. I don’t remember exactly how, but hopefully this helps. Alternatively, you could delete the loop and input the structure into modeller and ask

Dear CCP4BBers/RADDAMers Some of you may have noticed that the registration for the RD12 Workshop closed 2 weeks ago earlier than advertised, since we had already reached the capacity of the PSI room we had booked. We have now been able to move the Workshop to a bigger room, so registration is n
