Other Properties
DESCRIPTION
Cyanine3 Biotin is a dual-functional conjugate combining the bright fluorescence of Cy3 with the strong binding affinity of biotin for streptavidin/avidin (Kd ≈ 10-15 M). This non-sulfonated reagent is ideal for fluorescence-based detection, pull-down assays, and signal amplification in techniques like ELISA, immunohistochemistry, and DNA hybridization.
The biotin spacer arm (typically C5 or PEG) ensures optimal accessibility for streptavidin binding without fluorescence quenching. For aqueous applications, sulfo-Cyanine3 Biotin provides enhanced solubility while maintaining nM-level binding affinity.
