[ccp4bb] crystallization plates and robotics

2010-03-10 Thread Engin Ozkan
Hi, everybody, We recently recognized a problem with our Innovaplate SD-2 (a.k.a. MRC 2-Well) plates from Hampton. Our last batch of Innovaplates have an inconsistent well height such that our crystallization robot (a Mosquito) cannot put protein in all the wells. When tested with an older In

Dear All, I have created this website MAHORI (http://felix.bioc.cam.ac.uk) to display ligand interaction with proteins in the PDB. There is a lot of room for improvement and I really hope to get feedback from the CCP4 community so that I can make it more useful to chemical biology, medicinal chemi

Dear Sivaraman I worked on some protein with DNA contamination recently. Adding DNase and increasing IMAC wash volume at the same time changed 280/260 ratio and yield reproducible protein crystals, not high resolution yetIn case your protein can't stand other treatment... (Sorry Tommi, I hit

[ccp4bb] Off-topic - Domain termini for construct design

2010-03-10 Thread Claudia Scotti
Dear All, I'd like to espress a protein for crystallisation as a whole, but also to try separate expression of its two domains. Although prediciting domain boundaires is not difficult, I know that it is worthwhile testing several constructs to improve espression in soluble form. In s
