Description

n-(m-Peg4)-N'-(Azide-Peg4)-Cy7 is a bifunctional, near-infrared fluorescent dye conjugate engineered for advanced bioconjugation and labeling applications. This compound matters for researchers and developers requiring precise, stable, and highly detectable linkages in complex biological systems. Professionals in pharmaceutical R&D, biotech, and diagnostic assay development need it to create targeted imaging probes, antibody-drug conjugates (ADCs), and other sophisticated biomolecular constructs.

Application

• Fluorescent Labeling of Biomolecules: Conjugation to antibodies, proteins, peptides, or oligonucleotides via click chemistry for in vitro and in vivo imaging.
• Antibody-Drug Conjugate (ADC) Development: Serves as a fluorescent linker-payload for tracking conjugate distribution, stability, and cellular uptake during ADC research.
• Live-Cell and In Vivo Imaging: Utilized in the synthesis of NIR probes for deep-tissue imaging due to the Cy7 fluorophore's emission in the near-infrared spectrum.
• Diagnostic Assay Reagents: Key component in developing high-sensitivity fluorescent immunoassays and molecular diagnostic tests.
• Polymer and Material Science: Functionalization of surfaces, nanoparticles, or hydrogels with fluorescent tags for tracking and characterization.
• Proteomics and Biomarker Discovery: Labeling agents for gel-based or microarray-based protein analysis and detection.
