| Thermo Scientific DyLight 350 Amine-Reactive Dye is an NHS ester-activated derivative of high-performance DyLight 350 used to fluorescently label antibodies and other proteins that are then used as molecular probes for cellular imaging and other fluorescence detection methods.DyLight 350is a derivative of aminomethylcoumarine acetate (AMCA) and has a higher fluorescence intensity than Alexa Fluor 350 and AMCA in many applications. The high water solubility of DyLight Fluors means that a high dye-to-protein ratio can be attained without causing precipitation of the conjugates. DyLight 350 Amine-Reactive Dye is also available as part of two antibody labeling kit sizes.DyLight 350 Amine-Reactive Dye is activated with anN-hydroxysuccinimide (NHS) ester moiety to react with exposed N-terminal α-amino groups or the ε-amino groups of lysine residues to form stable amide bonds. Learn more aboutNHS ester chemistry.Typical labeling reactions require DyLight 350 Amine-Reactive Dye to first be dissolved in anhydrous dimethyl formamide (DMF) or another suitable organic solvent before adding a specific molar amount of dye to an amine-free buffer containing the protein to be labeled. However, the high solubility of DyLight Fluors permits protein solutions to be added directly to specific amounts of the labeling reagent. This feature allows DyLight 350 Amine-Reactive Dye to be provided in multiple formats with flexible protocols to achieve efficient degrees of labeling.We also offer Standard and Microscale DyLight 350 Antibody Labeling Kits for fast and efficient fluorescent labeling of antibodies for use in fluorescence methods.The standard size kit contains all necessary components to perform three separate labeling reactions using 1 mg of IgG or similar quantities of other proteins. The microscale kit contains all of the necessary components to perform five separate labeling reactions using 100 µg of IgG. Both kit sizes include the Amine-Reactive DyLight 350 NHS-ester in convenient single-use vials as well as purification resin and spin columns for the preparation of ready-to-use conjugate. |
