[ccp4bb] density modification

2007-05-31 Thread Gina Clayton
Hi CCP4ers firstly apologies that this is slighty off ccp4 topic but does anyone know of a programme whereby I can use solvent flipping with multi domain masks in addition to a solvent mask for my phases i.e. not based on a model? I wanted to use CNS density_modify (my maps are currently from

Re: [ccp4bb] Bacterial induction at 18C

2008-04-30 Thread Gina Clayton
Raji aside from the possibilites of toxic protein as already mentioned.. we had great results with overnight induction at 20oC for a protein that was somewhat insoluble at 37oC. One thing that might work for you is to grow the cells to OD 0.5 then lower the temperature to say 18 or 20.

Hi there I quite like the Amicon stirred ultra concentration cell systems. You can put large volumes in, maximum 1 litre size, I think. As well you can attach an inert gas such as Argon or Nitrogen, for the gaseous pressure, this reduces oxidation of your sample while it concentrates.

2008-12-22 Thread Gina Clayton
Hi CCP4ers Apologies for the off topic... I have been trying to get hold of L-ribulose-5-phosphate (D- is readily available). Does anyone know where I can get such a compound? Thanks in advance for any suggestions and Merry Xmas! Gina
