DyLight 350 Dye and Kits
A brilliant blue-emitting dye that is ideal for labeling amine or sulfhydryl groups on target proteins for multi-color fluorescence applications. 


DyLight 405 Dye and Kits
An exceptional blue fluorescence-emitting dye for labeling amine or sulfhydryl groups on target proteins for fluorescence applications. 


DyLight 488 Dye and Kits
A green fluorescence-emitting dye for labeling amine or sulfhydryl groups on target proteins for a wide array of fluorescence-based applications. 


DyLight 550 Dye and Kits
A vibrant orange-to-red fluorescence-emitting dye with better performance than other rhodamine derivatives to label amine or sulfhydryl groups on target proteins. 


DyLight 594 Dye and Kits
A red fluorescence-emitting dye for multi-color applications with reduced bleedthrough and available for labeling amine and sulfhydryl groups on proteins. 


DyLight 633 Dye and Kits
A red fluorescence-emitting dye with physical properties comparable to other 633 dyes for labeling amines or sulfhydryl groups on proteins. 


DyLight 650 Dye and Kits
A vibrant far-red fluorescence-emitting dye that replaces DyLight 649 and shows comparable or improved performance compared to other dyes. 


DyLight 680 Dye and Kits
A near-infrared (IR) fluorescence-emitting dye for labeling amine or sulfhydryl groups on proteins for a broad range of applications.  


DyLight 755 Dye and Kits
A near-IR fluor that replaces DyLight 750, is invisible to the naked eye and increases the staining options when using infrared imaging systems. 


DyLight 800 Dye and Kits
A near-IR fluor that is invisible to the naked eye but increases the staining options when using infrared imaging systems. 


DyLight Specialty Dyes
Fluors with a wide range of spectral, solubility and quenching characteristics for applications requiring properties beyond those of our standard DyLight Dyes. 



Non-activated DyLight Fluorescent Dyes for use as fluorescence imaging controls and calibrators.
