used for Click chemistry to label alkyne-modified oligonucleotidesCy3 azide is a non-sulfonated dye ready for the use in Click Chemistry reaction which can be detected by various fluorometers, imagers, and microscopes. The reagent can be detected by naked eye on gels because of inherently high extinction coefficient. For biomolecule labeling, using of organic co-solvent to dissolve this molecular is necessary for efficient reaction. Product is available both as solid compound, and as 10 mM solution in DMSO. First, Cyanine dye should be dissolved in organic solvent and then added to a solution of biomolecule in appropriate aqueous buffer. Water-soluble version of this reagent is also available. Most derivatives of non-sulfonated cyanines have low aqueous solubility except for hydrochlorides of hydrazides and amines. In protein analysis, proteins labeled by Cy3 azide couple with Cy5 azide can substantially simplifies the target identification process than only one fluorescent dye [1].

used for Click chemistry to label alkyne-modified oligonucleotidesSulfo-Cy3 azide is a sulfonated, hydrophilic and highly water soluble dye for Click Chemistry. For labeling of various molecules in aqueous phase for brightness and photostability of fluorophore, sulfo-Cy3 azide is an ideal choice. Click reaction can be carried out in pure water without need to use organic co-solvent. For labeling proteins and even intact biological objects, no organic co-solvent is needed. In life science, the sulfonate groups make the Cy dyes soluble in water and also reduce fluorescence-quenching which can arise from dye–dye interactions. In vitro, sulfo-Cy3 azide was used for fluorescent microscopy staining. Human U87MG glioblastoma cells that overexpress uPAR were just stained by Cy3-AE105 conjugate [1].Reference:[1] Sun, L.  Gai, Y. Anderson, C.J.; Zeng, D.

作者:德尔塔 日期:2022-09-26

Cyanine5.5 hydrazide is a carbonyl-reactive near infrared dye. Hydrazides quickly react with carbonyl compounds, such as aldehydes and ketones, and form stable hydrazones. This reaction is useful for the preparation of labeled conjugates.Carbonyl groups in biomolecules can form spontaneously after oxidative stress or deamination of proteins. Alternatively, aldehyde groups can be specifically generated by periodate oxidation of sugar residues of glycoproteins, for example antibodies. Antibodies can be oxidized by sodium periodate and labeled with Cyanine5.5 hydrazide to form Cyanine5.5 labeled antibodies. Since sugar residues in antibodies are located far from variable, epitope-binding site, this method is particularly good for the labeling of antibodies.Cyanine5.5 is a near infrared fluorophore, an analog of Cy5.5®.
