N-(5-Amino-1-carboxypentyl)iminodiacetic acid, 1g

Aminobutyl-NTA was first used by Dr. Hochuli in 1987 to purify recombinant proteins (the “Histag” technique). Since then, the AB=NTA has become an indispensable tool for immobilizing proteins with high specificity on solid surfaces, such as glass or the gold electrode. A solid surface is modified by AB-NTA and bio-functionalized via Ni (II) with a genetically expressed protein bearing a hexahistidine extension at its terminus. The His-tag technique has become increasingly important, particularly in surface plasmon resonance and structural analyses of proteins by x-ray interference. Using the His-tag technique, Dr. Noji was able to directly observe the rotation of F1-ATPase by fluorescence microscope.
