Re: [ccp4bb] PEG MW vs. cryoprotectivity

2007-12-05 Thread Jennifer Cash
In our recent experience, larger PEGs work similarly to smaller PEGs as far as vitrification goes. Additionally, transferring crystals to a solution of increased PEG concentration (as compared to mother liquor) can substantially reduce the amount of cryo needed for freezing and can be more gen

Weights are the same. 5.4 has a lot of small bug fixes and performance enhancement and some added stability things. And some new features I am planning to announce soon. Since I am responsible, my extremely biased view is that 5.4 is better. Garib On 5 Dec 2007, at 13:05, Jianghai Zhu wrote:
