Fluorescent Labeling Reagents for Proteins 

Convenient kits and activated fluorescent dyes for labeling amines, sulfhydryls and other antibody or protein functional groups with FITC, fluorescein, rhodamine or one of several DyLight Fluors to create molecular probes for fluorescence imaging.




Fast and efficient kits for labeling antibodies with any one of seven high-performance DyLight Fluors (em/ex from 405-800 nm). Two convenient kit formats provide for labeling either 0.1 mg or 1 mg antibody samples. 
 

DyLight 350, 405, 488, 549, 633, 649, 680 and 800 Reactive Dyes are bright alternatives to Alexa Fluors (Alexa 488, Alexa 546, Alexa 555, Alexa 647, Alexa 680) and IRDye 800. They are also brighter and more photostable than CyDyes (Cy3, Cy5, Cy5.5).  
 

Thermo Scientific Sulfhydryl-Reactive DyLight Dyes are maleimide-activated derivatives of high-performance DyLight Fluors for fluorescent labeling of sulfhydryl-containing peptides, proteins and other biomolecular probes. 
 

Phosphine-activated DyLight Fluorescent Dyes for chemoselective labeling of azide-containing molecules using the Staudinger ligation chemistry. 
 

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

Activated fluorescein dyes and kits for labeling peptides, proteins, antibodies and other molecules at primary amines or sulfhydryls. 
 

Activated derivatives of rhodamine dye for labeling proteins, peptides, antibodies and other molecules. 
 

Activated derivatives of blue fluorescent AMCA (amino-methyl-coumarin-acetate) dye for labeling proteins and other molecules at primary amines, sulfhydryls, carboxyls and sugar groups. 
 

R-phycoerythrin (PE), a red-fluorescent protein that can be crosslinked to other antibodies or other molecules to produce conjugates having a broad absorbance peak and a large stokes shift. 
 

The same high performance dye removal spin-columns used in the Thermo Scientific DyLight Antibody Labeling Kits are now available separately.
