Flexible panel design for four-color immunofluorescence

24 Aug 2026

This flyer demonstrates how Alexa Fluor® 555 and Alexa Fluor® 568 secondary antibodies can be incorporated into four-color immunofluorescence workflows. Discover how these spectrally distinct fluorophores support flexible panel design, enabling simultaneous visualization of multiple cellular targets while minimizing spectral overlap. Explore example staining configurations, emission profiles and imaging results in HEp-2 cells that illustrate how Alexa Fluor® 555 or 568 can be combined with DAPI, Alexa Fluor® 488 and Alexa Fluor® 647 for effective multicolor fluorescence imaging.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Fluorescence SpectroscopyFluorometers and spectrofluorometers (also called fluorescence spectrometers) are used to measure the intensity and wavelength of fluorescent light emitted from a sample after excitation by illumination. Spectrofluorometers utilize monochromators to select the desired wavelengths, whereas filter fluorometers employ a set of filters. Spectrofluorometers for measuring steady-state fluorescence and lifetime fluorescence (or time-resolved fluorescence) are available, as well as fluorescence microscopes and microplate readers.
