(DB-410903)
Cyanine 5 NHS Ester is an intensely bright far-red fluorescent dye that is structurally identical to Cy5. Known for its exceptionally high extinction coefficient and strong signal generation, it remains one of the most fundamental and widely used fluorophores in life sciences.
Because it emits in the far-red spectrum, Cyanine 5 helps researchers completely avoid the natural background autofluorescence of cells and tissues. It is perfect for a variety of imaging applications, including confocal microscopy, flow cytometry (FACS), DNA microarrays, and highly multiplexed labeling panels.
Cyanine 5 Carboxylic Acid is a non-reactive Cyanine 5 dye used as a reference standard or for labeling peptides and proteins. Its carboxyl group can be activated (e.g., sulfo-NHS, TFP) or modified via carbodiimide chemistry for conjugation to amino groups. It’s commonly used in solid-phase peptide synthesis with activators like HATU.
Package size
Key Parameters: Great brightness and pH stability with lower costs
Carboxylic Acid: Ideal as a reference standard or for further synthesis
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 at a more accessible price. It serves as a direct, highly economical substitute for Alexa Fluor® 647 when extreme photostability is not strictly required.
Complete Compatibility – Can be used in any existing protocol that uses Cy5
