Dear CCP4 users,
I'm looking for the diffraction image viewer, which will be able to
display of resolution circles and export it to new image. I tried use
idiffdisp, but after choose of the Show/clear resolution circles, there
is no action. Images were collected using Rayonics MX-225 detector -
Hi Rafal,
have you try ADXV ?
I never try to use idiffdisplay, but i know that ADXV can display
resolution circles.
If your software is able to open the image, but can't show the circles.
I think it's not really a problem with the image format, but with the
information in the Header of
iMosflm can certainly do this for you. You might have to screen grab to capture
the resolution rings though.
Tony.

Dear bulletin board,
A two-year post-doctoral position is available from September 2013 at the
Department of Medical Biochemistry and Biophysics (MBB), Karolinska Institutet,
Stockholm. The project deals primarily with over-expression, purification,
crystallization and structure determination
30% glycerol or 25% glucose should be sufficient for 1-2 M ammonium sulfate.

Hi Faisal,
3 - 3.5M Ammonium sulphate with your buffer should work too.
Take a small loop.

Hi Faisal,
if your solvent channels are smaller than 40A in the largest dimension
(most are) you can use a mesh loop to pick up the crystal and then wick
away all of the mother liquor. You can then flash cool your crystal
without having to transfer the crystal to another solution. Good luck,
The version of ADXV we have has some nice resolution ring features.
There is a mode with the typical 5 rings of evenly spaced resolution.
There is Anchor1 which draws a circle about the beam centre and
through a selected point. There is Pick3 which constructs a circle
from 3 selected points.
Just to follow up, the paper that was attached is based on the far more
original work by Garman and Mitchell

cryoprotection of 50 typical protein crystallisation solutions. J.Appl. Cryst.
29, 584-587.

Matt,
with this technique, how do you prevent crystal from drying up (other
than doing it fast)? I know Thorne's group does this trick under oil.
If you take no extra precautions, do you have an estimate of how often
diffraction is destroyed by this?
On the other hand, it's quite possible
Dear CCP4BB followers,
We are currently trying to obtain ligand-bound complexes for one of our
proteins by soaking and/or co-crystallisation. We have had prior success for
this protein, but using a different class of ligands. The new ligand (in DMSO)
remains in solution (more or less) when
Hi Klaus,
- small molecular weight PEG's e.g. 200 instead of DMSO, has the advantage of
also helping to cryo protect
- Methanol (only for dispensing the compound into wells) then allow to
evaporate and simply add your cryo-protected crystals, the hope is that
sufficient of your ligand goes
Dear Klaus,
We've had a lot of luck with ethylene glycol and isopropanol, using them
successfully in cases where DMSO affects diffraction.

Hi Ed,
good question. I have found that you have a good 30 seconds to remove
the surrounding liquid - so while you have to do it fast you have enough
time that it doesn't need a robot and even a malcoordinate such as
myself can do it. I'm afraid that I have no estimate for how often

liquor but quite often it occurs at relative humidity values where the

from the tip of a acupuncture needle. At least this works for many of

Dear Umri,
I think the main problem is co-crystallization.
What I would do is crystallize protein and antibody separately and then soak
protein crystals into reservoir solution containing antibody or vice versa.
And do try to get crystals from different conditions which may alter the space
