I'm still using passive, interleaved 3D, Zalman-style... Hopefully coot etc will retain support for that...! To unsubscribe from the CCP4BB list, click the following link:

We have seen a similar thing once, where we obtained proteins crystals simply by dehydration of the drop: Sharpe, M. L., Baker, E. N., and Lott, J. S. (2005) Crystallization of a protein using dehydration without a precipitant. Acta Crystallogr Sect F Struct Biol Cryst Commun 61, 565–568.

Thanks to everyone who responded, on and off the list. I thought I'd post a quick summary. To clarify my question slightly (if belatedly) I'm specifically looking for a passive 3D solution to plug into my MacBook Pro whilst on sabbatical in the USA. I'll be using it for a mixture of 2D and 3D

Re: [ccp4bb] Stereo monitors for use with Pymol and Coot

2014-03-05 Thread Shaun Lott
A rather US-centric question on passive 3D monitors... I'm just getting set up in the US, and I'm surprised on how few passive 3D monitors seem to be around - many models seem listed as 'out of stock' when looking in the usual places (Amazon, NewEgg, BestBuys, Walmart etc.) The best deal I

Yep - works fine on Coot and Chimera. Others may correct me, but I don't think Schrodinger have re-instated support in PyMol? I use it daily - the Zalman is the primary monitor on my desk. The great advantage of this type of monitor (IMHO) is that it is hardware independent.

Re: [ccp4bb] Nanodrop versus Nanophotomter Pearl versus good old Bradford.

Just to add my 2c worth... The department here has a couple of nanodrops as a shared facility, one for DNA/RNA and one for protein. It has been noticeable that over time people has been getting decreased reliability of measurements on the latter machine cf cuvette measurements, presumably due

Re: [ccp4bb] Using chaperones to boost expression in E. coli

2011-04-22 Thread Shaun Lott
As with all these things, YMMV. In our experience, chaperone co-expression can help not at all, can produce more folded protein or can produce more soluble protein, with co-purifying chaperone. With GroEL/S at least, chaperone release is easy (add ATP) and sometimes results in the liberation

Re: [ccp4bb] domain boundary, new fold, structure-based sequence alignment

2009-10-18 Thread Shaun Lott
In my experience, DALI can be better than SSM at detecting distant structural similarities. You might also want to try CE. To decide if a fold is 'new' rather than 'old but decorated' often boils down to a somewhat subjective call, but asking Alexei Murzin is as good a way as any to decide :-)

Re: [ccp4bb] heavy atom derivative choice

2009-07-15 Thread Shaun Lott
For gel-shift assay, do people normally use a special gel tank for heavy metal work? We used to use a Pharmacia Phast system, as this is bufferless and made it very easy to contain heavy metal contamination. Ours caught fire and died a couple of years ago, and I have yet to find a good cheap
