Fluorescence Staining of Cell Nucleus

DAPI is an organic dye which binds strongly to DNA. DAPI emits a blue fluorescence (Maximum fluorescent wavelength; 461 nm) by the irradiation of UV light (Maximum excitation wavelength; 358 nm).
HeLa cell nucleus stained with DAPI·2HCl [A2412] has been observed by fluorescent microscopy.


HeLa cells were fixed with 4% paraformaldehyde, and permerabilized with 0.2% Triton X-100.
HeLa cells nuclei were stained with 1 µg/mL DAPI [A2412] solution.
