[ccp4bb] Can I add PEG or Li2SO4 into protein sample for new screen?
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
Re: [ccp4bb] Can I add PEG or Li2SO4 into protein sample for new screen?
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? 03.06.2013 10:56, Qing Shi ?: Hi everyone, I wonder if I can add PEG or Li2SO4 into protein sample for new screen?

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

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: http://www.maxlab.lu.se/node/206 /Derek On 3 Jun 2013, at 17:25, Tim Gruene t...@shelx.uni-ac.gwdg.de wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Probably brighter than an XFEL if you average over a reasonable amount of time greater than fs ;-) Tim On 06/03/2013 05:13 PM, Jacob Keller wrote: Brighter than XFEL?
