Figure 6 Immunoblot of claudin 2 in HT‐29/B6 cell monolayers after 24 h of treatment with interferon γ (IFNγ, 1000 U/ml), tumour necrosis factor α (TNFα, 100 ng/ml) or without treatment (control). Signal intensity of the 22‐kDa claudin 2 specific band from the untreated control was set as 100% and was compared with cytokine‐treated cells on the same blot. Values represent means (SEM).
