Figure 4From: Intracellular expression of toll-like receptor 4 in neuroblastoma cells and their unresponsiveness to lipopolysaccharideEffect of LPS on IκB-α degradation in NB-1 cells. NB cells were cultured with LPS at 100 ng/ml for various time and cell extracts were analyzed with immunoblotting using anti-IκB-α antibody. Densitometric analysis of each IκB-α band was performed by a CS analyzer (top). A typical experimental result of three independent experiments is shown.Back to article page
