I. [Product Description]
    BSA-PEG-NI-NTA is an efficient organic intermediate based on the covalent coupling of bovine serum albumin and polyethylene glycol. It combines the metal chelation properties of nickel-nitrilotriacetic acid (NI-NTA) and can serve as the core catalyst for the directional immobilization of biological macromolecules. This product achieves the synergistic optimization of protein stability and PEG steric hindrance through precise design and is suitable for high-selectivity biological coupling and affinity purification systems.
