We have the suspicion (after several heavy FEDEX failures) they just toss
them around ... then the neck easily breaks off.
That only explains everything we have seen with completely damaged samples,
lost, flying around the dewar etc ...
When trying to communicate seriously with FEDEX about these is
Dear Sorin, many thanks for this. Very useful.
By probing the conformational space around the model, I meant to try and
predict how specific solvent conditions may (or may not) induce
rearrangement, both intra and intermolecule, within an oligomeric
multidomain protein compared to it in a crystall
That's a good point...
I was thinking that a decent crystal has a size in the hundreds of
micrometers (say 100 in a, b and c). So, with such a specimen we can use
any MX beamline.
But if the crystal is smaller (say 10 micrometers in a, b and c) You must
use a microfocus beamline.
*Please correct me
Hello community,
We recently had a dry shipping dewar fail catastrophically (while en route to
the beam line, so, major trauma). I sent it to a company that specializes in
repair and refurbishing of cryogenic tanks, and they told me it has an internal
leak, and hence is not reparable. I was exp
I agree with Phil. We did not consider sources to be "micro-focus" until we hit
70 microns or so in projection, circa 1999 for rotating anodes and a bit
earlier for sealed tube sources.
It was Uli Arndt's paper, Focusing optics for laboratory sources in X-ray
crystallography, J. Appl. Cryst. (1
Dear Andre,
I am not sure what you mean by conformational space around the model, but
to answer your question: short energy minimization can be done using, for
example, deep view/swiss pdb viewer. However, I think that you are most
likely looking for a short bout of molecular dynamics, in which yo
Dear colleagues,
could you please suggest a computational tool to perform energy
minimization of a crystal structure under explicit solvent conditions (i.e,
types and concentrations of ions, pH)?
I want to observe the solvent effects on the conformational space around a
starting model, all-atom,
I'm fairly sure that the 300-ish micron focus on my old (and retired) Rigaku
RuH3R home system - a perfectly good workhorse - was consider micro-focus by
precisely nobody.

Since we commonly consider nanofocus a beamline that can go below 1 micron, I
would say anything below 1mm for the sake of uniformity.

Hmmm…maybe not. ‘Multiplicity’ in crystallography is context sensitive, and not
uniquely defined. It can refer to
a. the position multiplicity (number of equivalent sites per unit cell,
aka Wyckoff-Multiplicity), the only (!) cif use

Dear colleagues,
The 2020 CCP4 School at APS has been cancelled. Due to the pandemic, it is not
possible to find a timeslot for the gathering at Argonne for the rest of the
year. We are very sorry for the inconvenience.
We want to thank the registrants for their interest in the School. The
