[ccp4bb] O/T: use of heparin in crystallisation

[Chen, Yu Wai]

Dear All,

Does anybody has any comment on using heparin as an additive to 
co-crystallise an RNA-binding protein?  I am not asking about using it 
to form a complex with proteins that are know to bind heparin 
specifically, but using it as a general RNA analogue, when we lack the 
knowledge of the RNA target sequence.

Thanks a lot.

Wai
