NTA-PEG-Biotin (Nitrilotriacetic Acid-PEG-Biotin) is primarily used in affinity chromatography for purification of His-tagged proteins. The NTA moiety chelates metal ions (e.g., Ni2+) that are immobilized on a solid support. His-tagged proteins can then be selectively bound to the column via metal affinity, allowing for purification in a one-step procedure. It can also be employed in biosensors and analytical techniques for the detection and quantification of metal ions in environmental samples or biological fluids. Its ability to chelate specific metal ions allows for sensitive and selective detection, which is crucial in environmental monitoring and industrial process control.
