The ability to immobilize biomolecules onto solid supports is a cornerstone of many biotechnological applications, including the development of biosensors, diagnostic arrays, and affinity chromatography columns. N-(3-Dimethylaminopropyl)-N'-ethylcarbodiimide hydrochloride (EDC HCl) plays a critical role in achieving this immobilization, leveraging its carboxyl-activating properties. NINGBO INNO PHARMCHEM CO.,LTD. provides reliable EDC HCl for these sophisticated applications.

The immobilization process typically involves a carboxyl-functionalized surface or a biomolecule with accessible carboxyl groups. EDC HCl is used to activate these carboxyl groups, forming a reactive intermediate. This intermediate then readily reacts with amine groups present on the target biomolecule (e.g., proteins, antibodies) or on a surface linker, forming a stable amide bond and anchoring the biomolecule. This method is highly effective for creating functionalized surfaces used in enzyme-linked immunosorbent assays (ELISAs), surface plasmon resonance (SPR) sensing, and the preparation of affinity matrices for protein purification.

The mechanism is similar to that seen in peptide synthesis and general bioconjugation. The activated carboxyl group on the support or linker molecule reacts with the amine groups of the biomolecule, creating a covalent link. Often, N-hydroxysuccinimide (NHS) is used in conjunction with EDC HCl to form a more stable NHS-ester intermediate, which can improve the efficiency and longevity of the immobilization process. This strategy ensures that the biomolecule remains securely attached to the surface, maintaining its activity and functionality.
