Source for Dye Affinity Chro. kits

[ron tate]

I hope someone can point me in the right direction, a few months back I 
thought I was seeing an ad in some journals for a Dye Affinity 
chromatography kit.  It had small columns with different dyes to use for 
pilot runs in determining which dye column would be useful for purifiing 
your favorite protein.  Now I am interested in it and cannot find it 
anywhere.  Was I just dreaming? 

Thanks in advance
