[ccp4bb] Can I add PEG or Li2SO4 into protein sample for new screen?

2013-06-03 Thread Qing Shi
Hi everyone,
I wonder if I can add PEG or Li2SO4 into protein sample for new screen?
Because  optimization seems no good result, initial crystal was got in
Bis-Tris, PEG8000, Li2SO4. If it is OK, then what's the concentration of
PEG or Li2SO4?
  Best regards,

Shiqing

Hi, Shiqing,
In my opinion, it is not good idea.
If you want to optimize the protein buffer than you could look at 
thermofluor method of protein buffer optimization.

BTW, have you tried seeding?

Brighter than XFEL? Or is it going to be an XFEL?

Probably brighter than an XFEL if you average over a reasonable amount
of time greater
than fs ;-)

Thanks Tim! But seriously, MAX IV will, as well as being a synchrotron, have a 
Short Pulse Facility at the end of its linac:

http://www.maxlab.lu.se/femtomax

By world's brightest light source of course I loaned a management slogan, but 
MAX IV will be a 3 GeV facility with emittance around 0.25 nmrad, which is a 
factor of 4 better than PETRA-III and will, at least as long as records tend to 
hold (i.e. not long), have the best specs in the world:
