Sulfo-Cyanine5.5 NHS ester is an amine-reactive active ester of a sulfonated far-infrared Cyanine5.5 fluorophore (an analogue of Cy5.5). This reagent is the preferred choice for labeling antibodies, sensitive proteins, and other substances in reactions that require a pure water environment or minimal addition of organic co-solvents. The dye is highly suitable for non-invasive in vivo near-infrared imaging and applications that demand a low fluorescence background.

Cyanine 5.5 NHS is a reactive dye for the labeling of proteins, and antibodies and small molecular compounds.

Sulfo-Cyanine 7 NHS 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[1]. CY dyes are of en used for the labeling of proteins, antibodies and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction. Below, we introduce the labeling method of protein antibody labeling, which has certain reference significance.

Cy5-SE (Cy5 NHS Ester) is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides. This dye requires small amount of organic co-solvent (such as DMF or DMSO) to be used in labeling reaction. This reagent is ideal for very cost-efficient labeling of soluble proteins, as well as all kinds of peptides and oligonucleotides. This reagent also works well in organic solvents for small molecule labeling. Excitation (nm):649, Emission (nm): 670.

Sulfo - Cyanine 3 NHS, a water - soluble and amine - reactive compound, can efficiently label proteins and polypeptides in pure aqueous solutions without the need for organic co - solvents. This makes it an ideal option for proteins with low solubility and those prone to denaturation. Moreover, the Sulfo - Cyanine 3 NHS ester can serve as a substitute for Cy3, Alexa Fluor 546, and DyLight 549, offering a practical alternative in various experimental and research settings.
