[ccp4bb] Off Topic- Cystine Detection

[Yuri Pompeu]

Dear All,
I am trying to probe the existence of a disulfide bond on the surface of my 
protein.
I have attempted Ellman´s and my results were not as clear as I would have 
hoped for.
I am not a sulfur/cysteine chemist and would appreciate the advice on what 
experiments to try!
Thanks a bunch
