I would like to draw your attention to a protein structure position advertised on the AstraZeneca jobs web pages. This is a permanent position in a recently formed structural biology team at our site in Boston, Massachussets. The position would suit an all-round, hands-on crystallographer. The w

Yes, the problem is with 32-vs-64. At first, I have found an ugly workaround of getting 32-bit version of libguile-srfi-srfi-1-v-3.so.3 and changing the symbolic link in /usr/lib to fool coot into using it. Coot will start but will be quite unstable. So to answer your question, there is no decent

[ccp4bb] Bubbles on crystals

2009-07-06 Thread kumar
Dear members, I have protein crystals grown in a condition with Isopropanol (13%) and citric acid (0.2 M). When I transfer the crystals to cryo-buffer (30% glycerol or 25% ethyleneglycol with 0.25 M citric acid and 13%-15% Isopropanol), small bubbles appear on the surface of the crystals. These ti

Thanks to all who helped with this, especially Paul Emsley, Ed Pozharski, Robert Orru, Partha Chakrabarti, and Michael Strickler. Here is a brief summary of the results: 1. It's easy to compile Coot for 64-bit Ubuntu 9.04 using the autobuild script *IF* you have all the the prerequisites. S

Just to add to this post, we've been successfully running Coot on 64 bit Ubuntu 9.04 using the X86 Centos-5 stable build (0.52) from Paul Emsleys's site: http://www.ysbl.york.ac.uk/~emsley/software/binaries/stable/ The only quirk I have found so far is that the window will flicker on and off whe

Hi, If you're worried - instead of transfering the crystal, just flood the entire drop with excess of your cryo buffer. No exposure to air this way. I bet that the bubbles won't go away though :) Artem > Dear members, > I have protein crystals grown in a condition with Isopropanol (13%) and > ci

Perhaps the bubbles are related to the bubbles which form when mixing alcohols with water, e.g., when making coomassie destain? And what are those bubbles, by the way? Jacob *** Jacob Pearson Keller Northwestern University Medical Scientist Training Prog

Those bubbles are mostly air - expelled out of the water by heat of mixing (simple alcohols and water generate fairly huge heat upon mixing). Crystalline sugars heat of mixing/dissolution is negative (which is why tea gets cooler when you add sugar to it). Not sure what glycerol+water mixtures do i
