Localization of β-gal/18D6 fusion, M31, M32, and ATRX proteins in
mouse (F9/18D6) nuclei. Immunostaining of F9/18D6 nuclei with
antibody against β-gal (images on the far left and red in merged
images), together with antibodies against M31 (a), M32
(b), and ATRX (c) (second from left and
green in merged images), is shown. DNA was counterstained with DAPI
(second from right and blue in merged images). Colocalized signals
appear as white.
