I am now using TALON and Pharmacia's chelating Sepharose FF charged

- Capacity: not very different.
- Purify: better than Sepharose.
- Leakage of metal: worse than Sepharose.
- Activity: better than Sepharose.
  (Note: My protein is very sensitive to EDTA, high salt and pH
   change.  Protein can be eluted at lower imidazole conc from TALON
   than from Sepharose.  This may make the difference in the

I consider that the metal charged to TALON is the trick.  Does anyone
know what it is?
