Description

3-Maleimidobenzoyl (Digoxigenin-3-o-Succinamido)Aniline is a specialized heterobifunctional crosslinking reagent designed for the conjugation of biomolecules. This compound is critically important for creating stable, site-specific linkages between proteins, peptides, or antibodies and other molecular probes or solid supports. It is primarily needed by researchers and manufacturers in the fields of bioconjugation, immunoassay development, and diagnostic kit production, where precise and reliable covalent attachment is required.

Application

• Bioconjugation Reagent: For the covalent coupling of digoxigenin-labeled molecules to proteins, antibodies, or peptides via amine groups.
• Immunoassay Development: Used to create enzyme-linked immunosorbent assay (ELISA) components and other diagnostic assay reagents.
• Diagnostic Kit Manufacturing: A key intermediate in the production of test strips and lateral flow devices for medical and veterinary diagnostics.
• Affinity Chromatography Ligand Synthesis: For immobilizing specific ligands onto chromatography resins for protein purification.
• Fluorescent Probe and Label Synthesis: Enables the creation of advanced fluorescent or chemiluminescent detection probes for microscopy and flow cytometry.
• Drug Delivery System Research: Facilitates the study of antibody-drug conjugates (ADCs) and targeted therapeutic delivery mechanisms.
