DyLight™ Dyes
DyLight dyes give you outstanding immunofluorescence results in flow cytometry and microscopy.
- More intense fluorescence and sensitivity than comparable spectral conjugates
- Greater photostability than other fluorochromes
- Good stability over pH 4 - 9
- Ideal for immunofluorescence techniques
- Compatible with all common fluorescence detection channels
- Available for custom conjugation

DyLight dyes are excellent alternatives to Alexa Fluor®, CyDye® and LI-COR® fluorescent dyes. DyLight dyes provide intense fluorescence and sensitivity requiring less conjugated antibody to study your cells than FITC and RPE, saving you money.
They are primarily suitable for use in immunofluorescence techniques such as microscopy and flow cytometry though may also be used in ELISA, Western blotting, high throughput screening and other array platforms.
Their absorption and emission wavelengths are compatible with popular fluorescence instrumentation, so you won’t have to change your preferred method of imaging.
We currently offer the following DyLight dyes conjugated to primary antibodies and secondary antibodies, and they are also available for custom conjugations to the antibody of your choice.
| Dye | Laser excitation line (nm) |
Maximal absorbance (nm) | Maximal emission (nm) | Suggested laser | Fluores- cence color |
