Cyanine3 Amine is a primary amine-functionalized derivative of the Cy3 fluorophore, designed for covalent conjugation to carboxyl groups via carbodiimide (EDC/NHS) chemistry. This non-sulfonated reagent serves as a versatile building block for custom probe synthesis, offering a reactive -NH2 group for coupling to activated esters, aldehydes, or epoxy-modified surfaces.
The amine spacer (typically C6 or PEG) provides optimal distance between the dye and target molecule, minimizing fluorescence quenching. For applications requiring water solubility, sulfo-Cyanine3 Amine is recommended.
Key Specifications:
• Reactive Group: Primary amine (-NH2, pKa ~9.5)
• Conjugation Chemistry: EDC/NHS, glutaraldehyde, or SMCC crosslinking
• Applications: Microarray printing, biosensor fabrication, polymer modification
