(DB-411001)
Cyanine 5.5 is a near infrared (NIR) fluorescent dye that is structurally identical to Cy5.5. Known for its exceptionally high extinction coefficient and emission in the NIR spectrum, it is a premier choice for researchers needing to push beyond the limits of standard visible fluorophores.
Because NIR light significantly reduces scattering and absorption by biological tissues, Cyanine 5.5 offers extraordinary deep-tissue penetration. It is perfect for a variety of demanding applications, including in vivo small animal imaging, deep-tissue confocal microscopy, and highly multiplexed flow cytometry panels.
Package size
Key Parameters: Upgrade your in vivo assays with exceptional deep-tissue penetration and lower costs
Exceptional Brightness: Cyanine 5.5 features a massive molar extinction coefficient (typically >250,000 M⁻¹cm⁻¹). This highly efficient light absorption generates a brilliant near-infrared signal ideal for detecting low-abundance targets.
Applications: In vivo small animal imaging, deep-tissue confocal microscopy, flow cytometry (FACS), near-infrared Western blotting, and cell/tissue labeling.
Cost-effective protocol compatibility: Offers the exact same spectral properties and performance as standard Cy5.5 at a more accessible price. Serve as a direct, highly economical substitute for near-infrared dyes like Alexa Fluor® 680.
Superior Deep-Tissue Penetration: Emitting at 695 nm, Cyanine 5.5 operates in the "near-infrared window" where biological tissues are most highly transparent. This drastically reduces background autofluorescence and light scattering, allowing for crystal-clear imaging deep within intact tissues and live animals.
