Sulfo-Cyanine3 Streptavidin is a fluorescent dye conjugate, commonly used in molecular biology and biochemistry for fluorescent labeling and detection in biotin-avidin systems.
Key Features:
- Fluorescence Properties: Excitation at ~550 nm, emission at ~570 nm. Bright, photostable, and hydrophilic due to the sulfonated dye.
- Affinity: High-affinity binding to biotin (Kd ~10^-15 M).
- Applications:
- Immunoassays (ELISA, Western blot, etc.)
- Microscopy (confocal, fluorescence imaging)
- Flow cytometry
- Biotin-labeled nucleic acid and protein detection.
- Water-Solubility: Enhanced by sulfonate groups, suitable for aqueous environments.
Storage and Handling:
- Store at -20°C, protected from light.
- Handle with care to preserve fluorescence.
Ideal for highly sensitive and specific detection in biotin-streptavidin systems.
