Article Snippet: Samples (50 μgr in 5× loading buffer) were then loaded into SDS-PAGE gels (12 or 15%) and transferred onto nitrocellulose membranes using the Mini-PROTEAN ® Tetra System (BIO-RAD) for 1 h. Membranes were incubated for 1 h with blocking solution (5% milk in TBST) and then probed overnight at 4°C with mouse anti-BDNF (1:2000; Icosagen; 327-100 clone 3C11), rabbit anti-p75 (1:700; Alomone Labs; ANT-007), rabbit anti-TrkB (1:700; Alomone Labs; ANT-019), and rabbit anti-proBDNF (1:2500; Genocopoeia) in TBST.
