Primary antibodies: rat BrdU (AbD Serotec, MCA2060GA, 1:500), rabbit GFP (Invitrogen, A11122, 1:300), rabbit Complexin-1 (Proteintech, 10246–2–AP, 1:300), mouse GFAP (G6171, 1:500), mouse Nsf-1 (MA1–12435, 1:300) and rabbit Syn3 (OSS00018W, 1:300) from Thermo Scientific, guinea pig Iba1 (234 004, 1:500), mouse Syt1 (105 011, 1:300), guinea pig ZnT3 (197 004, 1:1000) from Synaptic Systems.
Secondary antibodies. Antibodies (all obtained from Jackson Laboratory, donkey anti-guinea pig IgG (H+L) ML, #706-225-148 and 706-175-148; donkey anti-mouse IgG (H+L) ML, #715-225-151, 715-165-151, and 715-175-151; donkey anti-rabbit IgG (H+L) ML, #711-225-152, 711-165-152, and 711-175-152 were diluted 1:400. Confocal scans were carried out using a LSM 510 Imager Z.1 microscope (Zeiss) using Plan-Apochromat 63X/1.4 and EC Plan-Neofluar 40X/1.30 oil immersion objective lenses and four excitation laser lines. Tile scans were performed using a LSM 710 confocal microscope (Zeiss) with a Plan-Apochromat 20X/0.8 objective.
