fluorophore-conjugated antibodies.
Synaptophysin (red) and microtubule-associated protein 2 (MAP2; green) in mouse cortical neurons were fluorescently labeled with specific primary antibodies and Thermo Scientific DyLight 649-Conjugated Goat Anti-Rabbit or DyLight 488-Conjugated Goat Anti-Mouse Secondary Antibodies, respectively. Nuclei in both panels were labeled with Hoechst dye.
