SpectraDye Antibody Labeling Kits

Fluorescently label antibodies in one easy step



Fluorescently label antibodies in one easy step

SpectraDye Antibody Labeling Kits contain everything you need to produce covalently labeled, fluorescent antibodies in only 30 minutes. Choose from commonly used fluorescent dyes and label your antibody in a single step. Labeled antibodies are compatible with immunofluorescence applications including flow cytometry, Western blotting, and immunofluorescence microscopy so you can validate your results across multiple platforms using the same antibody.


  • Rapid – one-step labeling is complete in 30 minutes
  • Versatile – labeled antibody may be used in flow cytometry, Western blotting, or immunofluorescence microscopy
  • Flexible – choose from a broad set of commonly used fluorescent dyes
  • Save time and money – stop buying secondary antibodies; no more secondary antibody incubations and washes
  • Save antibody – the labeling reaction requires as little as 10 μg of antibody

SpectraDye Antibody Labeling Kits include sufficient reagents to label up to 1 mg of antibody. SpectraDye dye kits contain Antibody Labeling Buffer, SpectraDye Dye Solution, Quenching Solution, and Neutralization Buffer. The user-supplied dye kit does not contain dye, but does contain high-quality DMSO to prepare your own dye solution.
