Product Description
CY3-YNE (Sulfo-Cyanine3-alkyne) is a dye that may be utilized to label soluble proteins, peptides, and oligonucleotides/DNA. CY3-YNE is a reagent for click chemistry. It has Alkyne groups and could undergo CuAAc (copper-catalyzed azide-alkyne cycloaddition reaction) with compounds bearing Azide groups.
CY3-YNE (Sulfo-Cyanine3-alkyne) is a sulfonated cyanine dye functionalized with a terminal alkyne group, designed for copper-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry. It is a fluorescent dye used for labeling soluble proteins, peptides, and oligonucleotides/DNA. The sulfonate groups enhance water solubility, making it suitable for biological applications. CY3-YNE is commonly used in fluorescence imaging, molecular tracking, and quantitative bioanalytical assays requiring stable fluorescent tagging.
Biological Activity I Assay Protocols (From Reference)
Targets
CY3-YNE does not have a specific biological target; it is a chemical tool for bioconjugation. The alkyne group serves as a bioorthogonal handle for selective conjugation to azide-functionalized molecules via CuAAC click chemistry. Its primary "target" is the chemical functionality of azide-containing compounds. The cyanine fluorophore provides fluorescence for detection and imaging applications.
ln Vitro
CY3-YNE's in vitro activity is assessed by its efficiency as a click chemistry reagent. It is used to label biomolecules such as proteins, peptides, and oligonucleotides. The labeling efficiency is typically evaluated by measuring fluorescence intensity after conjugation. The compound's reactivity in CuAAC reactions is monitored by HPLC, LC-MS, or fluorescence spectroscopy. CY3-YNE exhibits good photostability and bright fluorescence, making it suitable for various bioanalytical assays.
ln Vivo
In vivo applications of CY3-YNE are primarily related to its use in bioorthogonal labeling for imaging. The compound can be conjugated to targeting ligands or nanoparticles for in vivo fluorescence imaging. Its sulfonated structure may limit cell permeability but improves water solubility. Detailed in vivo activity data are limited as the compound is primarily a chemical reagent.
Enzyme Assay
CY3-YNE is not a drug targeting biological macromolecules, so standard enzyme/receptor binding assays are not applicable. Instead, its chemical reactivity is assessed using CuAAC click chemistry reactions. Typical protocols involve mixing the compound with an azide-functionalized molecule in the presence of a copper catalyst (e.g., CuSO4) and a reducing agent (e.g., sodium ascorbate) at room temperature or 37degC. Reaction progress is monitored by TLC, HPLC, or mass spectrometry. Conjugation efficiency is calculated by comparing the relative amounts of starting materials and products.
Cell Assay
Cellular assays for CY3-YNE involve evaluating its utility for cell surface or intracellular labeling. Cells are incubated with azide-modified biomolecules (e.g., sugars, proteins) to incorporate azide groups metabolically, followed by reaction with CY3-YNE via click chemistry. Labeling is detected by fluorescence microscopy or flow cytometry. Cytotoxicity of the compound or its conjugates is assessed using standard cell viability assays such as MTT. The compound's labeling specificity is evaluated by comparing fluorescence signals in treated versus control cells.
Animal Protocol
In vivo animal studies for CY3-YNE are limited, as the compound is primarily a chemical reagent. When used in vivo, the compound is typically conjugated to targeting moieties and administered to animal models for fluorescence imaging studies. Tissue distribution and labeling efficiency are assessed by imaging or tissue analysis. The compound may be used in pre-targeting strategies where azide-modified antibodies or nanoparticles are administered first, followed by CY3-YNE for bioorthogonal labeling. Detailed in vivo protocols are not extensively reported.
ADME/Pharmacokinetics
Pharmacokinetic properties of CY3-YNE are characteristic of fluorescent cyanine dyes. The compound has a molecular weight of 667.84 and a molecular formula of C34H41N3O₇S2. The sulfonate groups enhance aqueous solubility. The compound is typically stored at -20degC, protected from light. Its pharmacokinetic properties are highly dependent on the specific conjugate to which it is attached. Detailed PK parameters such as half-life and bioavailability are not extensively reported for this reagent.
Toxicity/Toxicokinetics
CY3-YNE is a research reagent and not intended for human therapeutic use. The compound contains an alkyne group, which is generally stable under physiological conditions. In cell-based assays, the compound is typically well-tolerated at concentrations used for labeling. The cyanine fluorophore may have some phototoxicity upon prolonged light exposure. Standard safety precautions should be followed when handling this compound.
Additional Infomation
