Antibody for His-Tag

[Jim Beasley]

I am looking for a paper or ad for an antibody that recognizes the 6-histidine
tag.  I saw it recently, but now I can not find it.  A rep for a company I
contacted mentioned that she saw it as an ad in Nature, but I have been unable
to locate it.
	I would appreciate any help in finding any information about a antibody for
his-tag.  You can contact me via e-mail at beasley at berthaw.princeton.edu
