Re: [ccp4bb] O/T: microscopes
I can only recommend the Motic microscopes. i'm very impressed for $1,70O incl camera, not as sturdy as Leica (my favorite) but very good image quality. Drawback: no cold light source. But you can get a gooseneck light and do top illumination. Do not buy their polarizer, though. Cheers, Jens n Wednesday 17 December 2008 07:34:31 Uwe Mueller wrote: Dear Clint, Jerome is right. Do not expect to get a stereo microscope (these are more or less two microscopes within a smart arrangement) for this price. We purchased recently a Leica M205A, which defines the quality and price for a high-end system.

Dear All, Does anybody has any comment on using heparin as an additive to co-crystallise an RNA-binding protein?

[ccp4bb] Depositing coordinates with riding hydrogens
Hi all- Just wondering what the consensus is - should a structure refined with riding hydrogens be deposited with the coordinates for the hydrogens included? One could argue that, since they were used in the refinement to obtain the model and statistics reported, they should be included in the deposited pdb file. On the other hand, the presence of hydrogens in the pdb file might lead some to think the hydrogens were refined against density when they really weren't. Thoughts? Thanks, Jon

It doesn't hurt to include them, bu I don't see much point in it. The riding-model parameters are sufficient to regenerate the hydrogen positions. Of the things one might worry about not including in a PDB file, I'm more concerned about the omission of scattering factors used for refinement and the continuing ambiguity of the precise meaning of the B factor reported in the ATOM record.

Re: [ccp4bb] Depositing coordinates with riding hydrogens
Hi Jon, - obviously, the model should not be manipulated once the final statistics is obtained, or if it is manipulated, then the final statistics must be re-calculated; - I can't imagine someone thinking that hydrogens were refined individually in a X-ray structure say at 2A resolution. - also, it's much easier to remove H atoms later on, rather than add them back the *exact same *way you did. I don't see any logic of making the depositing information artificially less complete by removing hydrogens. Cheers, Pavel.

[ccp4bb] CCP4 6.1.0 release and CCP4MG
Hi After all v6.1.0 did arrive before Christmas :-) Thank you all. Still I guess Santa, after freezing in the car park, still had to endure beeing stuck in some chimney, as a consequence of all of us who wanted to grab a fresh copy, flooding poor CCP4 server. So, after 2 days I finally wgetted my 1 Gigabyte Lin-RH8 copy for installation in Ubuntu. Even before installing, I browsed all the tarball and couldn't find CCP4MG? Since the documentation states it should be a separate package (like COOT), am I missing something? Also, if you choose a custom tarball, there is no option to include CCP4MG. Thank you Victor Alves Dear All as we continue our journey up the A65 (towards the heart of Yorkshire) we are pleased to announce the release of Clapham (or 6.1.0). This is available form the usual locations http://www.ccp4.ac.uk/download/downloadman.php or ftp://ftp.ccp4.ac.uk/ccp4/6.1/ Obviously special thanks to the program authors, testers etc. Go enjoy Please note that the downloads are large (very large if you include the balbes database), so there may be an issue of browsers timing out (observed for firefox so far).

Re: [ccp4bb] LDAO SDS-PAGE
Besides the K-SDS precipitation it can also be the problem of membrane proteins generally having a tendency to aggregate when boiled with SDS. Try to just add the Laemmli buffer and load the gel without boiling. This is the general procedure for membrane proteins.
