| The Thermo Scientific DyLight 594 Antibody Labeling Kit contains an NHS ester-activated derivative of high-performance DyLight 594 used to fluorescently label antibodies and other proteins that are then used as molecular probes for cellular imaging and other fluorescence detection 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.DyLight 594provides vibrant red fluorescence with better performance than Alexa Fluor 594 and Texas Red dye for fluorescent 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 594 Amine-Reactive Dye is available as a stand-alone reagent or as part of two antibody labeling kit sizes.DyLight 594 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 594 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 594 Amine-Reactive Dye to be provided in multiple formats with flexible protocols to achieve efficient degrees of labeling. |

DyLight Antibody Labeling Kits provide outstanding recoveryThe percent recovery for DyLight Antibody Labeling Kits is the average for 16 labeling reactions using three different antibodies. The percent recovery for DyLight Microscale Antibody Labeling Kits is the average for 13 labeling reactions using three different antibodies. Immunofluorescence microscopy using DyLight 594 dyeCytokeratin 18 (red) in A549 cells was fluorescently labeled using an anti-cytokeratin 18 primary antibody and DyLight 594-Conjugated Anti-Rabbit Secondary Antibody. Thermo Scientific Pierce Hoechst stain was used to fluorescently label cell nuclei. Procedure summary for DyLight 350 Antibody Labeling KitsThe protocol is simple and provides efficient labeling, exceptional clean-up and excellent antibody recovery. |
