Western blot anlaysis of extracts from HeLa cells, untreated or TNF-α-treated (#2169, 20 ng/ml) for the indicated times, using Phospho-NF-κB p65 (Ser536) Antibody #3031 (top) or NF-κB p65 Antibody (bottom).
Western blot analysis of extracts from HeLa cells transfected with nontargeted (-) or targeted (+) siRNA. p65 was detect using NF-κB p65 Antibody #3034, and p42 was detected using p42 MAPK Antibody #9108. The NF-κB p65 Antibody confirms silencing of p65 expression, and the p42 MAPK Antibody is used to control for loading and siRNA specificity.
