Mosflm works fine with our Pilatus 2M at DLS - however you do need to
be using the beta-test version.

Using an envelope or a mask to start phasing even with high NCS is still worse
than using a low res model from cryoEM that is characterized by an (almost)
proper density distribution.
One has to measure the intensities of the very low res reflections (0 0 1 and
the likes) precisely.

Hi CCP4bb,
I have two dataset from one crystal with different distance.now i am wondering
how to merge the two dataset into one file,and use it to refinement.
thanks a lot!

Hello Deng,
Process them as usual with e.g. Mosflm, then sort them together (you
may need to rebatch one of the runs) and do one Scala run - this will
put all of the measurement on a common scale and write out data
suitable for refinement. For pointgroups with ambiguous origin choices
(e.g. P4)
Dear ccp4,
I have a case of PTS and wonder what's the best strategy to handle my data.
I processed my data in C2 with a=161 b=109 c=225 beta=104. The data in

Dear Vincent,
The easiest thing for you to do right now in the CCP4 context is to run Molrep,
with the flag for PTS turned on. If that works and gives a clear solution,
that's great. If not, then I'd suggest downloading a recent version of Phenix
and trying the new version of Phaser that
There are 3 options:
1) Use molrep. If you have two copies related with PST then it can give right
solution
2) Take the latest version of phaser and use it. It can deal with PST with two
related copies also
3) Reduce cell dimensions (it does not seem to be possible in your case. PST is

That difference density looks too good to be true..
There is obviously a very strong non-crystallographic translation.
Is the spacegroup and/or cell correct?

It will not be able to guess the number og H atoms associated with the RNA
so the answer will be a bit out.

Dear CCP4bbers,
Is there any tool to calculate the Matthews coefficient from a
crystallographic model
I would try molrep - it will detect the NC translation and use it..

Hi Min,
Please try this way if you use your protein for crystallization.
1. collect the needle and run SDS page or FPLC to verify the presence
of protein. Make sure it is not a buffer salt.
2. You don't need to do dialysis to remove b-ME, otherwise it will
take too long and you may lose some
Min,
I forgot one more thing.
If you try to grow crystall of membrane protein and get tiny crystal,
you may try to add 5~10% IPA + 5mM NH4SO4 to addjuct the surface
charge of your protein.
The crystall may get larger. Folks like this trick.
Good luck.

Dear ALL;
Thanks a lot for all the instructive suggestions. As my first trial, I
tried 0.1%Triton X-114 plus Ni-column binding buffer.
However, the oligomer of my protein got dissociated in to monomers as
indicated by gel-filtration.
Does anyone know how to

As an alternative strategy to avoid endotoxin, I plan to express the
protein in mammalian cells.
As suggested by others, the typical vector is pcDNA3.1(+). Does anyone
