About
Iminodiacetic acid (IDA) is a widely used chelating agent for preparing metal affinity chromatography media, particularly for immobilized metal affinity chromatography (IMAC) applications. By coordinating metal ions such as nickel or copper, IDA serves as a key component in affinity systems used for the purification of His-tagged proteins and other biomolecules. GoldBio offers research-grade IDA to support chromatography media preparation, method development, and protein purification research.
