[ccp4bb] Protein purification and crystallization position available in the Fesik Lab at Vanderbilt University

2015-03-11 Thread Phan, Jason
An opening is available in the laboratory of Dr. Stephen Fesik (http://www.mc.vanderbilt.edu/fesiklab) for the Research Associate position in structural biology and drug discovery. The candidate must possess a degree in biochemistry or a related field with 1-2 years of experience in protein

Hi Stephen, we crystallized several proteins in a glove box placed in a room with air condition. We checked the temperature all the times and found that is had been quite stable. For one protein that crystallized only at 4 deg C, we setup the crystallization plate within the glove box and

Hi Jacob: If you can find a copy of R. W. James, THE CRYSTALLINE STATE VOL II: THE OPTICAL PRINCIPLES OF THE DIFFRACTION OF X-RAYS. Hardcover – 1965, this gives a very good (albeit primarily classical) description. Blundell and Johnson also has a good, slightly more modern, description, which

Hi, Molprobity is also a nice software to do this kind of analysis - if you use it as implemented in phenix you also get good visualization in coot. I also asked the pymol community to create an implementation for pymol, but I did not follow if somebody took that up. Also this 'protein

Thanks for all of the responses, there seems to be no real consensus, but I have discovered: 1 There are several small incubators supplied by - Molecular Dimensions, Revsci, Centeo 2 Good air conditioning may negate the need for an incubator. 3 A Glove box may not even be necessary depending

Several have mentioned James to me, and I have had and read a copy for quite some time. I find, however, that the descriptions are more mathematical than mind-pictures. While math is more agnostic, I find mind-pictures more prognostic and helpful to me. But I absolutely love James. Somebody

Dear CCP4BBer's Apologies for the off-topic post, but the CCP4BB seems to be the best place to ask about crystallisation. I am looking to set up crystallisation in an anaerobic glove box and wondered how other people did this, specifically the crystallisation stage. My initial thoughts were

Dear Steve, There is a model of small incubator that fits through the large portal of a Belle Technology rigid glovebox - as an aside, that’s a good box for crystallisation and crystal manipulation since you can get the microscope-mounted side box with a dewar port for rapid and pretty

Dear Steve, You should not require an incubator if you have good, stable air con. We routinely grow crystals in plates stored at room temperature in wall mounted cabinets in our crystallisation lab. Another of the groups here have experience of growing crystals in an anaerobic box.
