NTA (Nitrilotriacetic acid) is a commonly used metal chelating ligand that has excellent affinity toward Nickel, copper, iron and many other metal ions. Biopharma PEG offers a variety of NTA PEG products that can react with amines, thiols and many other other groups. These reactive NTA PEGs can be used to attach to resins, particles and array surface. Our functional NTA PEGs can be directly used for molecule capture, detection and identification. PEG linker between NTA and other functional groups offers better water solubility, reduced steric hindrance and enhanced stability.
