[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? 03.06.2013 10:56, Qing Shi ?: Hi everyone, I wonder if I can add PEG or Li2SO4 into protein

Brighter than XFEL? Or is it going to be an XFEL? JPK On Mon, Jun 3, 2013 at 10:36 AM, Derek Logan derek.lo...@biochemistry.lu.se wrote: Hi, If anyone fancies becoming Life Science Director at the world's brightest light source, look no further than here:

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
