Structural Formula

Product Description
Dithiobis(C2-NTA) is utilized for the modification of a gold surface to introduce NTA groups that can bind most heavy metal ions. It forms SAMs similar to the other alkanethiols. The SAMs prepared using Dithiobis(C2-NTA) are highly unidirectional due to its alkyl chain interactions. Ni(II)-NTA chelates are commonly used for Histidine-tagged (His-tag) protein purification or separation. Therefore, Ni(II)-NTA-coated gold can be used for His-tag protein analyses. Dithiobis(C2-NTA) is soluble in water and alcohol. It is also referred to as disulfide-NTA in some papers.
