Description

2,4-Dichlorophenoxyacetic Acid Sulfo-n-Hydroxysuccinimide Ester Sodium Salt is a specialized, water-soluble active ester derivative of the auxin herbicide 2,4-D, designed for efficient bioconjugation. This compound is engineered to facilitate the covalent attachment of the 2,4-D moiety to amino groups in proteins, peptides, or other biomolecules under mild aqueous conditions. It is an essential reagent for researchers and manufacturers in the life sciences, particularly for creating immunogens, probes, and affinity matrices for analytical and diagnostic applications.

Application

• Immunogen Preparation: Conjugation of 2,4-D haptens to carrier proteins (e.g., BSA, KLH) for antibody production in agrochemical immunoassays.
• Diagnostic Probe Development: Labeling of antibodies, enzymes, or other detection molecules to create reagents for ELISA, lateral flow assays, or biosensors targeting 2,4-D residues.
• Affinity Chromatography Ligand: Immobilization onto solid supports for the purification of specific antibodies or receptors.
• Biochemical Research: Tool for studying plant hormone signaling pathways and herbicide mechanisms of action through targeted protein modification.
• Pharmaceutical Research: Potential use in antibody-drug conjugate (ADC) linker exploration for targeted delivery applications.
