From our lab to yours: 
much better way to detect polyHistidine-tagged proteins!
We're an active cancer research lab, and we were frustrated with the long, tedious, expensive and unreliable process required for His-tag blots. We solved this common problem- and we're glad to share it with you! 
(All profits support our cancer research.)



Custom conjugation is also available, of Nanogold®, FluoroNanogold™, undecagold or colloidal gold to primary antibodies, peptides, small molecules, or other molecules.
