(DB-411006)
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.
Cyanine 5.5 Azide interacts with alkynyl derivatives of biomolecules in Click Chemistry reactions either in the presence of copper (I) catalyst (with terminal alkynes) or without catalyst (with cyclooctynes), leading to the formation of stable adducts.
Package size
Key Parameters: Great brightness and pH stability with lower costs
Azide: Reactive with terminal alkynes via a copper-catalyzed click reaction
Applications: Confocal Microscopy, Super Resolution Microscopy, Flow Cytometry (FACS), DNA/RNA microarrays, whole-animal imaging, cell cultures and tissue labeling.
Cost-effective protocol compatibility: Offers the exact same spectral properties and performance as standard Cy5.5 at a more accessible price. It serves as a direct, highly economical substitute for Alexa Fluor® 680 when extreme photostability is not strictly required.
Complete Compatibility – Can be used in any existing protocol that uses Cy5.5
