Buy 7-ADD (7-Aminoactinomycin D) For Research Use Only. Not Intended for Diagnostic or Therapeutic Use.
What is 7-ADD (7-Aminoactinomycin D)
7-Aminoactinomycin D (7-AAD) is a fluorescent chemical compound widely used in molecular biology and flow cytometry for DNA staining and cell viability analysis. It intercalates with double-stranded DNA, preferentially binding at GC-rich regions, resulting in strong red fluorescence emission. 7-AAD is membrane impermeant, allowing it to selectively stain dead or membrane-compromised cells in mixed populations. It is a valuable tool for assessing cell cycle, apoptosis, and viability in research contexts. This compound is intended strictly for laboratory use and not for therapeutic or diagnostic human consumption.
