Our labeling reagents enable researchers to create their own labeled biomolecule for use in immunochemistry, fluorescence in situ hybridization (FISH), cell tracing, receptor labeling, and cytochemistry applications as well as for probing biological structure, function, and interactions.
We also offer our fluorophores conjugated to a variety of antibodies, streptavidin, peptides, proteins, tracers, and amplification substrates optimized for cellular labeling and detection.

The fluorophore dashboard (sample below) allows you to visualize the performance of a selected fluorophore and determine whether it is suitable for your application and where it can be used to best effect. The dashboard provides a summary of key properties—more details are available on the product page.
- Initial brightness indicates the relative brightness of the fluorophore, which is a product of the molar extinction coefficient and quantum yield, both of which are specific to each fluor. Fluorophores with high initial brightness can be used to detect lower-abundance targets
- Photostability in buffer is a relative measure of the percentage of initial fluorescence intensity remaining following 30 seconds of continuous illumination using a 40x/1.4NA objective and a 100-watt Hg-arc lamp as the light source with samples mounted in phosphate buffer; high photostability in buffer is ideal for live-cell imaging and detection
- Photostability in antifade buffer is a relative measure of the percentage of initial fluorescence intensity remaining following 30 seconds of continuous illumination using a 40x/1.4NA objective and a 100-watt Hg-arc lamp as the light source with samples mounted in Invitrogen ProLong Gold or SlowFade Gold antifade reagent; high photostability in antifade reagent is ideal for fixed-cell imaging and detection
- Stain index is a normalized value that allows users to compare the brightness of various dyes in flow cytometry applications; it is derived by subtracting the mean fluorescence intensity (MFI) of the negative population from the MFI of the positive population and dividing the resulting value by twice the standard deviation of the negative population
- Laser line indicates the commonly used laser line(s) for detection using flow cytometry
- Common filter set indicates the standard microscope filter set that generates the best imaging results
- Excitation max indicates the peak excitation wavelength (see the Fluorescence SpectraViewer for a complete profile)
- Emission max indicates the peak emission wavelength (see the Fluorescence SpectraViewer for a complete profile)
- Performance in SRM is a normalized value that allows users to compare the brightness of various dyes in SRM applications; SRM determinations were made in the optimum buffer type for each dye (MEA, BME, or TCEP) as described in the SRM buffer table.
