reusing Ni NTA - (Aug/24/2009 )

Hello!
could someone tell me how to reuse my Ni NTA beads with the same protein? I want to get rid of the imidazole! I was told that I just had to wash 20% EtOH (for storage) away with water and then with buffer and I could use them again?

Thank you!

20% EtOH wash and then PBS will be fine :lol:
