Cy5.5 is an important historical fluorophore from GE Healthcare. It has an excitation peak at 678 nm and an emission peak at 695 nm. Spectrally its similar to Alexa Fluor™ 680.

Cy5.5 is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis.

Cyanine5.5 NHS ester is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides, an analog of Cy5.5® NHS ester. Cy5.5 is a far-red (and near-infrared) emitting dye which is ideal for fluorescence measurements where background fluorescence is a concern.

2021年7月20日 · Cy5 and Cy5.5 are both cyanine dyes with several differences between them. Used in Fluorescence Resonance Energy Transfer (FRET), Fluorescence Polarization (FP), and Time Resolved- Fluorescence Resonance Energy Transfer (TR-FRET).

2025年3月11日 · Cyanine 5.5 (Cy5.5®) dyes are used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. Call 800-990-8053 or send a request to [email protected] for bulk quote.

Peridinin chlorophyll protein-Cyanine5.5 (PerCP-Cyanine5.5) is a photostable tandem dye excited from the 488 nm laser. It is stable in fixative, and stained cells can be stored overnight. Less-abundant intracellular antigens stained with PerCP-Cyanine5.5 can often be reliably detected in multicolor flow cytometry experiments.

Type: Near-infrared (NIR) fluorescent dye molecule used in bioconjugation applications similar to CY5. High brightness: Offers strong fluorescence intensity for sensitive detection. Convenient conjugate labeling: Can be readily attached to biomolecules like proteins and antibodies.

Cy5.5 from VectorLabs is a near-infrared dye that offers benefits in applications where low background and deep tissue penetration are critical. The near-infrared region is characterized by very low autofluorescence from biological tissues resulting in a much higher signal-to-noise ratio.

Cy5.5 amine is a functionalized cyanine dye containing a free amine group, which can be conjugated with a variety of functionalities including NHS esters, epoxides and etc. Cyanine5.5 is a far red dye working great for live organism imaging and …

2025年2月28日 · PE-Cy5.5 is a popular color used in flow cytometry. Its primary absorption peak is at 565 nm with emission peak at~700 nm. The filter sets of 682/33 nm and 695/40 nm are recommended for this tandem color.
