[ccp4bb] OT: Crystallisation compatible detergents
Hello,
We can make a nice 1:1 complex
Hi Darren
I believe that the most frequently used detergent for protein
crystallization (not including membrane proteins) is octyl-glucoside.
The most important parameter is the CMC of the detergent and the size of the
micelles of free detergent if you have micelles around. These considerations

Hi Darren,
I'm not aware of any (membrane) protein crystal structures solved with tween20.
It's heterogeneous, and its color suggests it contains impurities and/or
oxidation products, making it

Hello,
We can make a nice 1:1 complex between two proteins that then gradually
precipitates during storage at 4 degC. With 0.005% Tween-20 the complex is
stable and does not preciptate noticeably.

measure the kinetics of binding by Biacore so it is clearly compatible
