Affinity column needed..

[Kim Hak-Sung]

Hello netters.

Recently, I am trying to purify an enzyme which needs NAD+ as a cofactor.
I heard that there're some affinity columns which can be used for 
this purpose. Any opinion would be a great help for me doing my project.

Information sent by private e-mail would be more appreciated..
