Nitrilotriacetic acid (Cat No.:R040220) is a chelating agent used to bind metal ions, forming stable complexes. It is commonly utilized in a variety of applications, including water treatment, industrial processes, and as a buffering agent in biochemical assays. NTA has a high affinity for metal ions like calcium, magnesium, and iron, which helps prevent metal-induced precipitation and maintains the stability of solutions. It is also used in protein purification, where it aids in the selective binding of histidine-tagged proteins, facilitating their isolation and analysis in research.
