7AAD

7-Amino-Actinomycin D (7-AAD) is ready-to-use nucleic acid dye solution (2 ml). 7-AAD can be used in place of propidium iodide (PI) for the exclusion of nonviable cells in flow cytometry analysis. This product can be used in combination with PE (phycoerythrin), and FITC (Fluorescein isothiocyanate) conjugated antibodies in 2-color analysis. The advantage of 7-AAD over PI is the minimal spectral overlap between these emissions. Fluorescence is detected in the far red range of the spectrum (650 nm long-pass filter).
