I just recently came across the Talon resin by Clontech. I have a large (500ml) bottle of Qiagen's nickel resin. Has anyone used the Talon (or any other resins)? What metal does it use? What advatanges have you realized (activity of the protein vs. non-activity?) Any feedback would be most welcome. Thanks, chuck miller oravaxcm at world.std.com
