Immunocytochemistry/ Immunofluorescence - Nuclear yellow (Hoechst S769121) (AB138903)
ICC/IF image of ab6046 stained HeLa cells. The cells were 100% methanol fixed and then incubated in 1% BSA / 10% normal donkey serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilize the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab6046, 1μg/ml) overnight at +4°C. The secondary antibody (orange) was ab150064 Alexa Fluor® 594 donkey anti-rabbit IgG (H+L) used at 2μg/ml for 1h. Nuclear Yellow (Hoechst S769121) (ab138903) was used to stain the cell nuclei (purple/blue) at a 250μg/ml dilution with a 60 minute incubation.

Product details
The Hoechst stains are a family of fluorescent stains for labeling DNA used in fluorescence microscopy and flow cytometry. Because these fluorescent stains label DNA, they are also commonly used to visualize nuclei and mitochondria.
The long-wavelength tracer Nuclear yellow is often combined with the popular retrograde tracer True Blue for two-color neuronal mapping. In neuronal cells, Nuclear yellow primarily stains the nucleus with yellow fluorescence, whereas True Blue is a UV light–excitable, divalent cationic dye that stains the cytoplasm with blue fluorescence. Both Nuclear yellow and True Blue are stable when subjected to immunohistochemical processing and can be used to photoconvert DAB into an insoluble, electron-dense reaction product.
