SH-SY5Y cells and VM organotypic cultures were treated with a lysis buffer and protein concentrations were estimated by the Bio-Rad protein assay using bovine serum albumin as standard, as previously described [10 (link)]. Specific primary antibody anti-iNOS (BD Transduction 610329; 1/500), anti-COX2 (Cell Signaling #4842 1/500), anti-Bid (1/500; Santa Cruz Biotechnology), anti-Bad (1/500; Santa Cruz Biotechnology), anti-IκBα (Santa Cruz Biotechnology sc-371; 1/500), anti-NFκB p65 (Santa Cruz Biotechnology sc-372; 1/500), anti-Bcl2 (Santa Cruz Biotechnology sc-7382; 1/500) and anti-Bax (Santa Cruz Biotechnology sc-7480; 1/500) were mixed in 1× PBS, 5% w/v nonfat dried milk, 0.1% Tween-20 (PMT) and incubated at 4°C, overnight. Signals were detected as described above [11 (link)].
