Fluorescent Antibody Labeling Kits
quick and easy kits to conjugate your antibody to Chromeo Dyes
Active Motif's Chromeo™ Antibody Labeling Kits enable you to label your antibodies and proteins with the superior fluorescence of our Chromeo Dyes. Convenient kits for labeling with the Chromeo 488, 494, 546 and 642 Dyes are available. Chromeo conjugates will exhibit a bright fluorescence and additional superior luminescence properties, like broad Stokes shifts, stability towards photobleaching and pH, and low cell toxicity.

Chromeo Antibody Labeling Kit advantages
- Easy – just mix dye and antibody
- Quick – labeled antibody ready in 1 hour
- Affordable – costs much less than custom orders
- Optimized – rely on Active Motif Chromeon expertise
Chromeo™ Dyes – Chromeo 488, Chromeo 494, Chromeo 546 and Chromeo 642 – are bright fluorescent labels that replace Alexa Fluor*, DyLight* or Cy*-dyes. They are compatible with most excitation sources including diode lasers, LEDs, tungsten lamps and xenon arc lamps.
Chromeo™ Dye advantages
- High intensity
- Photostability – the combination with MAX Stain™ reagents provides optimal fluorescent stability for multiple exposures and increased exposure time
- Room temperature incubations
- pH insensitive
- Low background
- Easy to use – no harsh chemicals required for conjugation
Fluorescent Chromeo Dyes serve as bright labels for antibodies and other biomolecules, enabling detection in immunofluorescence, high content screening, ELISA and FRET applications, as well as in flow cytometry.
