E. coli Cloning Strains for Molecular Biology: What They Are and Why They Matter
by Pallabi Roy Chakravarty, Ph.D.
Ni2+ ions give nickel agarose beads their characteristic blue color. This blue color can fade or disappear completely when loading his-tagged proteins onto the column....
Nickel agarose beads change from blue to a brown or black color when the nickel ions have been reduced from a Ni2+ to a Ni1+...
The GoldBio Floating Tube Rack is one of our more clever giveaways because of the unique purpose it serves. And, with it also being one...
The characteristic blue color of nickel agarose beads comes from the 2+ oxidation state of the nickel ions. Color is also a useful indicator for...
