Immunocytochemical localization of PSD-Zip45 in cultured
hippocampal neurons. At 21 days in culture, hippocampal neurons were
double labeled with antibodies for PSD-Zip45 (green; a,
d, and g) and PSD-95 (red; b),
synaptophysin (red; e), or the NR1 subunit of NMDA
receptors (red; h). The images were examined by confocal
microscopy. c, f, and i are superimposed
images.
