Re: [ccp4bb] Insoluble ligand?

Dear Ritcha, You could also try low molecular weight PEG's, e.g. PEG400 in fairly high concentrations. They often do a good job in solubilizing ligands and are usually much more crystal-friendly than e.g. DMSO. Best, Herman -Original Message- From: CCP4 bulletin board

I've bitched enough about all things Mac, but this one's just too good to pass on (from the article that Peter linked to): The fundamental issue here is Lion's assumption that you don't know what you're doing, and it's going to ensure you're protected from cock-ups that, in your ignorance,

Great! Maybe, they should add an extra term for correlation of Fcalc to Fobs (or LLG or R) to their game. I wonder, if structures could be solved ab inition by players, then :-). Best regards, Dirk. Am 19.09.11 12:33, schrieb Kevin Cowtan: Crystal structure of a monomeric retroviral protease

Listening to Jobs speak recently, I got the distinct impression that the end of the era of general desktop computers PC's may be on the horizon. Of course that's iPad sales rhetoric, but it may be that the public moves away from general computers and that surely will have implications for

First the C2221 cell is a version of the hexagonal with the 2-fold axes now aligned along the a=b 2-fold in the hexagonal. But I dont think you can define NCS properly without some knowledge of coordinates. If you have enough anomalous scatterers that might allow you to get a start. Does

That's progress! A century ago we'd need an infinite amount of monkeys typing on an infinite amount of typewriters to produce a single paper. Now we need just a finite amount of gamers to produce 7+ models to get one that looks quite like a folded protein. And it saved an heavy atom soak as
