Immunostaining of mouse blood buffy coat with various HP1 antibodies. Columns: DAPI (DNA staining); Cy3, antibody staining viewed by conventional epifluorescent microscopy. Note that the monocytic nuclei exhibit staining with all monoclonal anti-HP1 antibodies (Chemicon). Granulocytic nuclei only reveal staining with anti-HP1 γ, which appears more concentrated at pericentric heterochromatin. Scale bar: 10 μm.
