Description

Fluorescein-Peg3-(n-Boc)-Amine is a high-purity, bifunctional chemical linker featuring a fluorescein fluorophore, a triethylene glycol (PEG3) spacer, and a Boc-protected amine group. This compound is critically important for creating stable, fluorescently labeled conjugates in bioconjugation and diagnostic assay development. It is primarily needed by researchers and manufacturers in the fields of biopharmaceuticals, in vitro diagnostics (IVD), and proteomics for tagging antibodies, peptides, and other biomolecules.

Application

• Bioconjugation Reagent: For site-specific fluorescent labeling of proteins, antibodies, and peptides.
• Diagnostic Probe Synthesis: A key intermediate in the development of fluorescent probes and assay components for ELISA, flow cytometry, and immunohistochemistry.
• Biomaterial Functionalization: Used to introduce fluorescent tags and amine handles onto nanoparticles, polymers, and surfaces for tracking and further modification.
• Drug Delivery Research: Employed in the synthesis of fluorescent drug conjugates to study pharmacokinetics and cellular uptake.
• Life Science Research: A versatile tool for fluorescence microscopy, cell imaging, and molecular tracking experiments.
• Chemical Biology: Facilitates the study of biomolecular interactions and pathways through fluorescent tagging.
